主题

快速入门

Control System Designer Tuning Methods
You can tune compensators using various graphical and automated tuning methods.
What Blocks Are Tunable?
You can tune parameters in certain Simulink blocks using Simulink Control Design™ software.
Mark Signals of Interest for Control System Analysis and Design
Analysis points allow you to access to internal signals, perform open-loop analysis, or specify requirements for controller tuning in systems modeled in either MATLAB^® or Simulink.

设计工作流

Single Loop Feedback/Prefilter Compensator Design
Tune the closed-loop performance of a single-loop system using a feedback compensator, and then tune the system response to changes in the reference signal using a prefilter.
Cascaded Multiloop Feedback Design
To design compensators for cascaded multi-loop systems, first tune the compensator for the inner loop and then tune the outer-loop compensator.
Designing Compensators for Plants with Time Delays
Some Control System Designer design and analysis tools support exact time delays while others use approximations of time delays.
Tune Custom Masked Subsystems
To tune a controller within a custom masked subsystem, you can configure the subsystem as a tunable block.

Design Compensator Using Automated PID Tuning and Graphical Bode Design
Automatically tune the parameters of a PID controller. You can then fine tune the controller performance using graphical design techniques.
Tune Simulink Blocks Using Compensator Editor
Tune Simulink blocks using the Compensator Editor dialog box in Control System Designer.

分析和验证

Analyze Designs Using Response Plots
Analyze your control system designs using the plotting tools in Control System Designer.
Compare Performance of Multiple Designs
Examine the effects of different tuning methods or compensator structures by comparing the performance of multiple compensator designs.
Update Simulink Model and Validate Design
To tune a controller for a nonlinear system, Control System Designer linearizes the Simulink model. Therefore, it is good practice to validate your tuned controller performance using the nonlinear system.

Regulate Pressure in Drum Boiler

Use Simulink® Control Design™ software, using a drum boiler as an example application. Using the operating point search function, the example illustrates model linearization as well as subsequent state observer and LQR design. In this drum-boiler model, the control problem is to regulate boiler pressure in the face of random heat fluctuations from the furnace by adjusting the feed water flow rate and the nominal heat applied. For this example, 95% of the random heat fluctuations are less than 50% of the nominal heating value, which is not unusual for a furnace-fired boiler.
