摘　　要：论述了PMAC运动控制器的性能及其伺服控制功能;简述了直线电机的伺服控制策略;提出了基于PMAC的直线电机速度/加速度前馈控制算法;对算法中各个参数的作用做了简单的介绍,阐述了速度前馈和加速度前馈参数的性能及其调整。通过实验得到证明,引入适当的速度和加速度前馈,可较好地补偿系统的跟随误差,从而提高系统的性能。The functions and servo control functions of PMAC motion controller were introduced. The algorithm of velocity and acceleration control for linear motor based on PMAC was proposed. The functions of each parameter in the algorithm were simply discussed. The functions of velocity and acceleration feedback parameter and its adjustment were elaborated. It's demonstrated through experiment that the following error of system can be compensated with the adding of appropriate velocity and acceleration feedback and the function of system can be improved.
