Plot System Responses
To determine whether the compensator design meets your requirements,you can analyze the system response using the response plots. On the PIDTuner tab, select a response plot from the AddPlot menu. The Add Plot menu alsolets you choose from several step plots (time-domain response) orBode plots (frequency-domain response).
Convolution reverbs are reverb effects which use impulse responses (IRs) to simulate an acoustic space. These are the best freeware convolution reverb effects in VST plugin format for digital audio workstations on PC and Mac.

The Challenge of Interacting Tuning Parameters. Since Kc and Ti individually can make a controller more or less aggressive in its response, the two tuning parameters interact with each other. If current controller performance is not what we desire, it is not always clear which value to raise or lower, or by how much. Below is a complete. Analyze Design in PID Tuner Plot System Responses. To determine whether the compensator design meets your requirements, you can analyze the system response using the response plots. On the PID Tuner tab, select a response plot from the Add Plot menu.

Set the example.
For 1-DOF PID controller types such as PI, PIDF, and PDF, the software computes system responses based upon the following single-loop control architecture, where G is your specified plant and C is the PID controller:
For 2-DOF PID controller types such as PI2, PIDF2, and I-PD, the software computes responses based upon the following architecture:
The system responses are based on the decomposition of the 2-DOF PID controller, C, into a setpoint component Cr and a feedback component Cy, as described in Two-Degree-of-Freedom PID Controllers (Control System Toolbox).
The following table summarizes the available responses for analysis plots.
Response | Plotted System (1-DOF) | Plotted System (2-DOF) | Description |
---|---|---|---|
Plant | G | G | Plant response. Use to examine plant dynamics. |
Open-loop | GC | –GCy | Response of the open-loop controller-plant system. Use for frequency-domain design. Use when your design specifications include robustness criteria such as open-loop gain margin and phase margin. |
Reference tracking | (from r to y) | (from r to y) | Closed-loop system response to a step change in setpoint. Use when your design specifications include setpoint tracking. |
Controller effort | (from r to u) | (from r to u) | Closed-loop controller output response to a step change in setpoint. Use when your design is limited by practical constraints, such as controller saturation. |
Input disturbance rejection | (from d1 to y) | (from d1 to y) | Closed-loop system response to load disturbance (a step disturbance at the plant input). Use when your design specifications include input disturbance rejection. |
Output disturbance rejection | (from d2 to y) | (from d2 to y) | Closed-loop system response to a step disturbance at plant output. Use when you want to analyze sensitivity to modeling errors. |
Compare Tuned Response to Block Response
By default, PID Tuner plots system responses usingboth:
- The PID coefficient values in the controller block in the Simulink® model (Block response).
- The PID coefficient values of the current PIDTuner design (Tuned response).
As you adjust the current PID Tuner design, suchas by moving the sliders, the Tuned response plots change, while theBlock response plots do not.
To write the current PID Tuner design to the Simulink model,click . When you do so, thecurrent Tuned response becomes the Block response. Further adjustmentof the current design creates a new Tuned response line.
To hide the Block response, click Options,and uncheck Show Block Response.
Convolution reverbs are reverb effects which use impulse responses (IRs) to simulate an acoustic space. These are the best freeware convolution reverb effects in VST plugin format for digital audio workstations on PC and Mac.
An impulse response captures the sound of an acoustic space or an artificially simulated space (when recorded from a hardware reverb unit, for example). Loading an impulse response in a convolution reverb effect will apply the reverb properties of the sampled acoustic space to the processed audio signal. This way, we can simulate recording an audio track in a natural environment (by using impulse responses of outdoor spaces) or mimic the sound of expensive hardware reverb effects.
1. Convology XT by Impulse Record
Convology XT is a free convolution reverb VST plugin developed by Impulse Record. It includes a collection of 70 reverb impulse responses captured from a variety of vintage hardware reverb units. Additional impulse responses are available for purchase on the developer’s website. More importantly, the plugin is capable of loading external impulse responses in WAV format.
In terms of its ability to modify the loaded impulse response file, Convology XT is the most advanced freeware convolution reverb VST plugin on this list. The user can adjust the attack and decay time, pre-delay, and the frequency response. It is also possible to time-stretch the IR file and to apply modulation in order to achieve a stereo widening effect. The plugin doesn’t introduce any latency, which is somewhat of a rarity among freeware convolution reverbs.
Convology XT can be downloaded completely free of charge from Impulse Record’s website. After installing and loading the plugin for the first time, enter the serial number provided at checkout to activate your license. The developers have also provided several tutorial videos to help new users get started with the plugin.
More info:Convology XT(32-bit & 64-bit VST/AU/AAX plugin format for Windows & MacOS)
Pros
+ Plenty of control over the active impulse response
+ Can load external IR files
+ Plenty of control over the active impulse response
+ Can load external IR files
2. MConvolutionEZ Convolution by MeldaProduction
MConvolutionEZ comes with a wider range of impulse responses than Convology XT, but its feature set is less advanced. The user can adjust the stereo width of the active impulse response and shape its tone using a pair of filters. Unfortunately, the timing properties like attack and decay time can’t be customized. This is a serious drawback which makes MConvolutionEZ less of a professional mixing tool and more of a beginner option for users who are just getting started with using convolution reverb plugins. Still, its ease of use and intuitive user interface are part of the reason why we recommend giving it a try.
Much like Convology XT, MeldaProduction’s convolution reverb plugin can load external impulses responses in WAV and FLAC format. Due to the convenient file browser which is located at the very center of the user interface, MConvolutionEZ is a great tool for testing newly downloaded impulse response libraries. The included reverb impulses sound pretty good, too.
One thing we didn’t like, though, is the fact that MeldaProduction bundles all of their plugins into a single installer. This makes for longer download times and a somewhat annoying installation procedure. Also, the plugin will show a nag screen asking the user to upgrade to the paid version of the plugin which is called MConvolutionMB. The plugin’s functionality isn’t affected by the nag screen, though.

Pros
+ Fast workflow
+ Loads external IR files in WAV and Flac format

Cons
– Lacks envelope controls

3. SIR1 by SIR Audio Tools
SIR1 is an old product (released in 2004.), but some users still swear by it. Its simple user interface and a rather capable feature set make it a useful tool even in this modern age of VST plugins. However, SIR1’s biggest drawback is the fact that it is only compatible with 32-bit VST plugin hosts on Windows. Mac owners and Windows users running 64-bit digital audio workstations are out of luck.
The user interface is well designed, with the file browser on the right, waveform display on the top, the control parameters on the left, and the spectrum display on the bottom. The user can adjust the pre-delay time and the envelope of the loaded impulse response. The IR can also be time-stretched, which is a great feature to have in a convolution plugin. SIR1 has a fixed latency of 8960 samples and is optimized for low CPU consumption.

Pros
+ Time-stretching of the loaded IR file
+ Loads external IR files in WAV format
+ Time-stretching of the loaded IR file
+ Loads external IR files in WAV format
Cons
– Only supports 32-bit VST plugin hosts on Windows
– No longer updated

– No longer updated
4. Reverberate LE by LiquidSonics
Reverberate LE is another older plugin on this list (released in 2006.) and it shares the same compatibility issues with SIR1. In other words, it will only work in 32-bit digital audio workstations on Windows-based machines. If you happen to fall into that particular category of users, Reverberate LE is well worth a shot.
The plugin includes only a small collection of impulse responses, so it’s mostly up to the user to provide their own IR samples (WAV, AIFF, and FLAC files are supported). Once loaded, the impulse responses can be customized using the Reverberate LE’s envelope shaping and time-stretching controls. The plugin also features a parametric equalizer which can completely alter the tone of the IR sample.
Reverberate LE can operate in zero latency mode, or in low latency mode when the graphics card is used for processing (an Nvidia chip is required for this). Stereo impulse responses are supported.

Pros
+ Advanced envelope and time-stretching controls
+ Features a parametric EQ for shaping the tone
+ Advanced envelope and time-stretching controls
+ Features a parametric EQ for shaping the tone
Cons

5. Halls Of Fame 3 Free by Best Service
Halls Of Fame 3 Free is a stripped-down version of the Halls of Fame 3 – Complete Edition (€169) convolution reverb effect by Best Service which comes with over 1,500 reverb presets. The free version only includes 27 reverb presets and doesn’t load external impulse responses. The reason why we’re including it on the list, though, is that the included reverb impulse responses sound exceptionally good.
The plugin features a selection of impulse responses captured from legendary hardware reverb units such as the EMT 240, AKG BX 20, Lexicon PCM96, and the Bricasti M7. The presets can be customized using detailed envelope and tone control parameters. The user can adjust the pre-delay time, attack/release times, and trim the loaded impulse response. The plugin also features a 3-band tone control and a damping control for shaping the tone of the reverb tails.
