Classical Control Design

Design, tuning, and analysis of single-input, single-output (SISO) feedback systems

使用Control System Designerapp, you can interactively design and analyze single-input, single-output (SISO) controllers for feedback systems. You can design controllers using various graphical and automated tuning methods. To choose the best tuning method for your application, seeControl System Designer Tuning Methods.

For information about tuning SISO controllers in Simulink^®models, seeClassical Control Design(Simulink Control Design).

Feedback Control Architectures
When you open Control System Designer from MATLAB^®, you can select one of six possible control architecture configurations.
Design Requirements
Using Control System Designer, you can tune your compensator to satisfy various time-domain and frequency-domain design requirements.
Programmatically Initializing the Control System Designer
This example shows how to configureControl System Designerfrom the command line and how to create functions to customize the startup of aControl System Designersession.

Compensator Tuning

波德图设计
Bode diagram design is an interactive graphical method of modifying a compensator to achieve a specific open-loop response.
Root Locus Design
Root locus design is a common control system design technique in which you edit the compensator gain, poles, and zeros in the root locus diagram.
Nichols Plot Design
Nichols plot design is an interactive graphical method of modifying a compensator to achieve a specific open-loop response.
Edit Compensator Dynamics
Achieve your design goals by manually editing compensator poles, zeros, and gains.
Design Compensator Using Automated Tuning Methods
Tune a compensator using automated tuning methods in Control System Designer.

Compensator Tuning in金宝app

Tune Simulink Blocks Using Compensator Editor
This example shows how to tune Simulink® blocks using the Compensator Editor dialog box inControl System Designer.
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.
