Simulation of Single Neuron PID Control for Hydraulic Servo System

根据某型号精校机电液位置伺服系统的数学模型建立系统开环传递函数,针对电液位置伺服系统时变和非线性的特点,提出一种基于单神经元的PID控制方法。该控制方法综合了传统PID控制器算法简单和神经网络自适应能力强的优点。通过对电液位置伺服系统的控制仿真,仿真结果表现出该控制器较强的自适应性、鲁棒性等特点,达到了对液压伺服系统的自适应控制。

This paper presents a new control way bas.ed on the single neuron PID controller in view of the time-varying and nonlinear characteristics of this system.This controller combines both the advantage of classic PID controller＇s simple algorithm and the neural network＇s self-adaptive ability.After simulation for the electronic and hydraulic position servo system,it shows that this controller displays strong adaptivity and robustness.
