It is difficult for the traditional PID regulator to adjust parameters online in controlling complicated timevarying systems, and the gain is unable to be adjusted automatically and the response rate is lower for the single neuron PID regulator. A new single neuron adaptive PID regulator based on immune feedback mechanism is proposed and applied to PMSM AC servo system. The single neuron adaptive PID algorithm is employed as the speed closed-loop controller of servo system to fulfill real-time adjustment of the PID parameters, and the immune feedback mechanism is embedded to achieve self-adjustment of the gain coefficient and enhance the response rate. The simulations and experiments show that the control strategy effectively increases anti-disturbance capabilities and improves speed control effects of the system, thus the overshoot and oscillation get less, the response rate heightens,and the steady state error becomes smaller speed control, loading to better dynamical and steady state performances of speed control.
