Abstract
The design and development of controller for a precision positioning system using linear permanent magnet stepper motor (PMSM) for long travel range with submicron resolution is presented in this paper. Microstepping with proportional integral (PI) current control for PMSM is adopted for better positioning control. Phase currents are kept constant at any desired level by the PI controller. MATLAB-SIMULINK is used to simulate the system and the control algorithm is implemented on DsPIC30F4011 microcontroller. A suitable driver circuit is incorporated and the performance of the system is tested using horizontal length measuring instrument-“Labconcept Premier 1000”.
介绍了一种亚微米分辨率长行程线性永磁步进电机精密定位系统控制器的设计与开发。采用比例积分(PI)电流微步控制的永磁同步电机，实现了更好的定位控制。PI控制器将相电流保持在任意所需的水平上。采用MATLAB-SIMULINK对系统进行仿真，并在DsPIC30F4011单片机上实现了控制算法。设计了合适的驱动电路，并采用“Labconcept Premier 1000”水平长度测量仪对系统进行了性能测试。
