Study on Dynamic Characteristics and Rapid-positioning Control for a High-response Linear DC Motor

DU Zhi-qiang,ZHOU Zu-de,AI Wu,CHEN You-ping (Huazhong University of Science and Technology,Wuhan 430074,China)  
A high-response linear DC motor for rapid positioning control is considered.The construction features and the high-response characteristics of the linear DC motor are presented. The mixed digital-analog control system based on DSP is proposed, and the parameters of PID controller are designed by means of the critical proportion oscillation approach,the measured step response indicates that the settling time is less than 30 ms for 5 000 μm displacement.The experimental results show that the positioning error is in the ±12 μm range at 10 Hz working frequency for ±5 000 μm stroke.
