Research on Nonlinear Friction Compensation Control for AC Servo System
摘要
Abstract
In the position servo system of wide speed regulation ,large output of multi start and stop ,the traditional closed loop control is difficult to meet the requirement of high perform‐ance system .According to the AC position servo system with friction nonlinearity ,parameter un‐certainties and external disturbances and other issues ,the nonlinear friction model of servo sys‐tem model based on LuGre theory was established .Then nonlinear friction model takes into ac‐couny the nonlinear friction of drive screw and permanent magnet synchronous motor .A friction compensation algorithm based on the model was proposed ,The simulation and experiment results show that the nonlinear friction model can effectively describe the AC position servo system and the ,friction compensation control algorithm can effectively improve the tracking speed and track‐ing precision .关键词
