摘要: 在分析了位置伺服控制系统基本原理和数学模型的基础上,提出了一种单神经元PID/CMAC复合控制算法和控制器的设计方法。用单神经元PID替代常规PID控制,由神经元来在线调整PID控制参数,利用CMAC神经网络的自学习和自适应能力,来完成系统的实时控制。该算法直接应用于位置伺服控制系统,仿真结果表明,与传统PID控制算法相比较,该复合控制算法增强了系统的控制精度,提高了系统的响应速度,具有较强的鲁棒性和抗干扰能力。

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.
