Speed control of electrical drives using classical control methods

Authors:

Abstract
A classical-control approach to the design and analysis of proportional-integral (PI) speed controllers for electrical drives is presented. After vindicating the fact that traditional one-degree-of-freedom PI control generally gives unsatisfactory performance, a well-performing two-degrees-of-freedom PI controller is designed, with analytic parameter selection. The robustness of the obtained closed-loop system is analyzed, and is found to be satisfactory.
