Classical Control Design

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

Using the Control System Designer app, 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, see Control System Designer Tuning Methods.

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

Topics

Control Design Basics

Compensator Tuning

  • Bode Diagram Design
    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.
