When transient performance requirement is higher in the control system and single-loop control system can not meet the requirements, we implement the multi-loop control and parameter optimization in line with the inner loop to outer loop of the order. This article takes double-loop DC motor speed control system as an example, and uses simulation optimization methodology to design of two PI regulator...
Designed a parameter self-tuning PID-controller based on fuzzy control, which can adjust PID-parameters according to error and change-in-error. A simulation study of the system shows that the controller possesses both the precise character of PID controller and the flexible advantage of fuzzy controller. It can eliminate the steady error of the system promptly.
