Research on Detection and Control Optimized Approach for Permanent Magnet Servo Motors at Low Speed with Ordinary-Resolution Incremental Encoder
摘要
Abstract
Aiming at the shortcomings of traditional control method for permanent magnet servo motors, an optimal speed detecting and controlling approach at low speed range is presented with ordinary-resolution incremental encoder in this paper. An extended M/T method is adopted for improving the speed of detection precision at ordinary-low speed range, and an improved T-method with closed-loop tracking feedback is employed for realizing high-precision speed detection at ultra-low speed range and an adaptive Proportion-Integration controller of reference speed is applied for obtaining a better speed control performance. Finally, sufficient experiments are implemented by the proposed approach on DSP controller and permanent magnet brush-less servo motor. Experimental results demonstrate that the dynamic performance at low speed is greatly enhanced and the adjustable speed range is extremely expanded.关键词
