【 摘 要 】

This paper presents a new tuning method for P and PID controller in a double-loop feedback structures. The stability region is first determined by Routh-Hurtwitz stability criteria. Simple tuning rules are established to determine the optimal P/PID parameter values within the stability regions, to meet desired performance-robustness criteria. The effectiveness of the newly established tuning rules are evaluated via numerical study and compared with those based on the same existing PID tuning methods.
