Abstract

In Chapter 1, the PID control structures and components have been examined. In this chapter, simple methods for tuning the controller, i.e., selection of Kc, Ti and T d will be provided. These include a heuristical approach based on trial and error, and several classical systematic methods which involve conducting an experiment, determining a process model and using known tuning methods to determine the control gains instead of a trial and error basis. Systematic methods are worthwhile and necessary for certain cases:
  1. 1.

    Important loops where control performance is critical and important.

     
  2. 2.

    Difficult loops where trial and error methods, and the usual rules of thumb are not applicable or effective.

     
  3. 3.

    Slow loops which will take far too long time to test each new setting for trial and error methods to be feasible, in which case it is often worth calculating a setting using systematic approaches.
