The Design of Thyristor DC Speed Regulation System Based on Ziegler Nichols PID Control

Abstract:

In this paper, a method based on Ziegler Nichols - frequency response of the adaptive PID controller is proposed. The control circuit identifies online important critical frequency response characteristics of process object through input and output data in the normal process operation, and then the system online update PID controller parameters based on Ziegler - Nichols tuning rules or by the improved method. The adaptive process of PID controller does not require any prior knowledge of the system, but it can always guarantee control circuit run in the best condition. The results show that the method has stronger robustness and adaptive ability.
