PI/PID Controllers Design for Integrating and Unstable Systems

  • Chapter
PID Control in the Third Millennium

Part of the book series: Advances in Industrial Control ((AIC))

Abstract

In this chapter, methods for designing PI/PID controllers for integrating and unstable systems are summarized. Several examples of unstable and integrating processes are provided. A review on controller design methods, based on the direct synthesis method, IMC method, and equating coefficient method, is presented. Further, methods of calculating the set-point weighting parameter are given. Robust analysis is carried out using Small gain theorem and Kharitonov’s theorem. Simulation results are given on few case studies.
