| 摘 要： | 针对永磁直线电动机参数变化和外部扰动对伺服系统的影响,提出了自适应变结构位置控制设计方法。用电动机的位置误差信号及其导数构造切换函数,利用自适应律对系统不确定性扰动因数的极限进行估算。经过分析验证,与基于SVPWM的矢量控制系统相比较,自适应变结构位置控制算法明显减少了系统参数变化和外部扰动引起的推力脉动,能快速准确地跟踪给定信号,增强了整个系统的自适应性和鲁棒性。

| Abstract: | In view of the influence of servo performance for permanent magnet linear synchronous motors(PMLSM) drive system with parameter variations and external force disturbance,the project of adaptive variable structure position control is proposed.The limit of motor's position error signal and its derivative are used to compose the switching function,and the adaptive law is used to evaluate the limit of uncertainty disturbance factor of system.Through verification,comparing with vector control system based on SVP... |
