摘　　要：本文介绍了一种采用DSP芯片TMS32 0C2 4x实现的永磁同步电机磁场定向控制方案。所采用的磁场定向控制策略 ,在较宽的速度范围内有效。本文着重介绍了一种改进算法 ,即取消相电流传感器且采用滑模观测器实现无位置传感器速度控制。This document introduces a solution to control a permanent magnet synchronous motor using the TMS320C24x.The control method presented relies on the field orientated control (F.O.C).This algorithm maintains efficiency in a wide range of speeds by controlling the rotor flux directly. Within this report different enhanced algorithms are presented. Among the solutions proposed are ways to suppress phase current sensors and using a sliding mode observer for sensorless speed control.
