Overview of the SISO Design Tool

The SISO Design Tool is a graphical-user interface (GUI) that allows you to design compensators.

The SISO Design Tool is made up of the following:

• The SISO Design Task Node in the Control and Estimation Tools Manager, a user interface (UI) that facilitates the design of compensators for single-input, single-output feedback loops through a series of interactive panes.

• The Graphical Tuning Window, a graphical user interface (GUI) for displaying and manipulating the Bode, root locus, and Nichols plots for the controller currently being designed. This window is titled SISO Design for Design Name. The Graphical Tuning Window by default displays the root locus and Bode diagrams for your imported systems. The two are dynamically linked; for example, if you change the gain in the root locus, it immediately affects the Bode diagrams as well.

• The SISO Design Task-associated LTI Viewer (For instructions on how to operate the LTI Viewer, see LTI Viewer)

• A tool that automatically generates compensators using PID, internal model control (IMC), or linear-quadratic-Gaussian (LQG) methods.

• Optimization-based tuning methods that automatically tune the system to satisfy design requirements (available if you have Simulink^® Design Optimization™ software installed).

This tool is used extensively in the Control System Toolbox™ Getting Started Guide. In particular, you should read Chapter 4, "Designing Compensators," of that book to see how to do typical design tasks with the SISO Design Tool. This document, on the other hand, is a reference that describes all available options for the SISO Design Tool.
