摘要
对目前应用比较广泛的永磁同步直线电机(PMSLM),分析建立其数学模型。直线电机控制系统具有简化机械上的连接而增加电气控制上的难度的特点,在分析控制系统的结构后,提出通过对直线电机在运行过程中易变的参数进行辨识,然后在此基础上通过计算对控制器的输出进行补偿,从而达到更好的控制效果。利用MatLab软件仿真验证该方法相对传统的PID控制方法可以达到更好的控制效果。
Analyzes and establishes the mathematical module of permanent magnet synchronous linear motor（PMSLM）,which is commonly applied in industry nowadays.Linear motor control system has the feature of simplify the mechanical connection while harder the electrical control,after analyzing the structure of the control system,provides a more effective method,recognizes the parameters which may easily changed in system＇s performing,and with which to make a compensation for the output of the controller so that we can reach a higher performence.At last,uses MatLab software simulated and proves that this method can reach a better performance comparing with the traditional PID control method.
