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).

Control Design Basics
- Choosing a Control Design Approach
Control System Toolbox™ provides several approaches to tuning control systems.
- Getting Started with the Control System Designer
Tune compensators for a feedback control system using the Control System Designer app.
- Control System Designer Tuning Methods
You can tune compensators using various graphical and automated tuning methods.
- 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
Configure Control System Designer from the command line and create functions to customize the startup of a Control System Designer session.
- 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
Design a compensator for an electrohydraulic servomechanism using root locus graphical tuning techniques.
- 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 Simulink
- Tune Simulink Blocks Using Compensator Editor
Tune Simulink® blocks using the Compensator Editor dialog box in Control 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.
Systems with Special Characteristics
