大多数先进的制造工艺要求材料输送、包装、组装和电气布线的精确运动。为了实现精确的直线运动，这些高性能制造机床大多使用带有永磁旋转电机和旋转到直线联轴器的X-Y滑台。这种方法虽然应用最广泛，但存在精度低、机械调整复杂、成本高、可靠性低等缺点。介绍了一种用于制造自动化中高性能运动的直线开关磁阻电机的位置控制。所提出的执行器结构简单，易于制造。不需要磁铁，旅行距离也没有限制。该执行器非常坚固，可以在恶劣环境中使用。首次提出了一种新的电流-力-位置查找表来执行力的线性化。然后，采用H/SUB/SPL INFIN//环路整形设计的插入式鲁棒补偿器，提高了系统的鲁棒性和跟踪性能。运动系统的实验结果表明，该系统跟踪响应快，精度高。
Most advanced manufacturing processes require precise motions for material transfer, packaging, assembly, and electrical wiring. To achieve precise linear motions, most of these high-performance manufacturing machines use X-Y sliding tables with permanent-magnet rotary motors and rotary to linear couplers. Though this method is the most widely used, it has disadvantages of low accuracy, complex mechanical adjustments, high cost, and low reliability. This paper describes the position control of a linear switched reluctance motor for high-performance motions in manufacturing automation. The proposed actuator has a very simple structure and it can be manufactured easily. There is no need for magnets and no limitation on the travel distance. The actuator is extremely robust and can be used in a hostile environment. A novel current-force-position lookup table is first developed to perform the force linearization. Then, a plug-in robust compensator using H/sub /spl infin// loop-shaping design is employed to improve the system robustness and the tracking performance. Experimental results of the motion system indicate that the system has fast tracking responses with good accuracy.
