摘要:

本文针对常规PID伺服控制器设计时依赖精确数学模型同负载、模型参数的不确定性和非线性因素影响精确模型获得的矛盾,设计并分析了单神经元自适应PSD控制器。利用神 经元的自学习、自组织能力,根据被控对象的参数变化情况进行权值的在线调整,加入了增益的自适应学习算法,使得调节更方便。同时,对PSD算法快速性方面的不足,采用复合算法进行了一定的改进。仿真表明,所设计的自适应PSD伺服控制器在一直线电机伺服系统中获得了满意的结果。

Abstract:

Considering the big influence of load disturbance, model parameter uncertainty and nonlinear factors, a singleneuron adaptive PSD controller is designed and studied. Based on the self-learning and self-organizing ability of the neuron, the weight of the plant is adjusted online. Furthermore, the algor  ithm of self-regulating the gain is given. Meanwhile, the speed of the PSD algorithm is improved. The simulation results show that the adaptive PSD serv o-controller has a good performance.
