Abstract

Digital controller design methods and system identification techniques provide the basic tools for effectively solving a control problem. The final stages in the controller design are emphasized in this chapter. This involves implementation aspects, performance specifications and the interaction between plant identification and controller design.

The first part of the chapter reviews several topics related to the implementation of digital controllers: effect of the digital-to-analog conversion, effect of saturations, effect of the computational delay, manual to automatic switching, cascade control, performance evaluation, adaptation of controller parameters, the hardware for controllers implementation.

In the second part of the chapter, the joint use of system identification and controller design is illustrated through several examples:

  • Temperature control of an air heater

  • Speed control of a DC motor

  • Cascade position control of a DC motor

  • Position control through a flexible transmission

  • Position control of a 360° flexible robot arm

  • Deposited zinc control in hot-dip galvanizing (SOLLAC-Florange)
