Abstract: Based on analyzing rationale and mathematics model of a position servo control system，the paper introduces a new design of parallel control arithmetic and controller based on CAMC and PID.The method replaces PID by single neuron PID，achieves the on-line adjustment PID control parameter and realizes real time control on the system by the self-study and self-adaptive capability of CMAC neural network.This algorithm is applied in simulation research of the position servo control system.The result shows the system possesses the advantages of high precision，real-time standard，strong ability of anti-interfere and robustness.
