Abstract

QFT(Quantitative feedback theory) is a design method to synthesize robust controller, satisfying some design specifications. Loop shaping is regarded as one of the important steps in QFT design. In this paper, we present to apply the approximation algorithm for loop shaping to PID tuning. An example is used to illustrate its feasibility.
