Designing Compensators

This chapter discusses how to build compensators using functions from the Control System Toolbox. It begins with a description of the SISO Design Tool, a graphical user interface (GUI) that simplifies the task of designing controllers. Through two design examples, a DC motor and an electrohydraulic servomechanism, this chapter shows you how to use the SISO Design Tool to design compensators by root locus, Bode diagram, and Nichols plot design techniques, and how to analyze the resulting designs.

If you need to develop custom applications, or must perform MIMO (multiple input multiple output) design, the Control System Toolbox provides a set of commands that implement a variety of design algorithms, including root locus design, pole placement, and linear quadratic Gaussian (LQG) design.
