Application Studies of Immune PI Controller in Double Closed-Loop DC Speed Regulation System

摘要

In accordance with the biological immune system regulating law and comparison the control system and the immune system, a parallel immune PI controller is proposed in this paper. Based on control requirements of double closed-loop DC speed regulating system and conventional control strategies, this paper presents that the control mode of applying immune PI control to speed loop and applying PI control to current loop. The simulation results show that this method has the advantages of small overshoot and high steady precision, and can comprehensively improve the dynamic and steady performance of DC speed regulating system compared with the conventional PI control, therefore, it has a certain application prospect.
