永磁同步电机无传感器控制位置和速度的估算

Position and Speed Estimation in Sensorless Control of Permanent Magnet Synchronous Motors

用Microchip数字信号控制器,以软件的方式实现永磁同步电机的无传感器磁场定向控制,并说明了估算电机位置和速度的过程.其中电机的位置和速度是根据测量电流和计算电压估算的,而位置和速度估算器是基于电流观测器而构建的.

This paper illustrates a software- based implementation of sensorless field oriented control for permanent magnet synchronous motors using Microchip digital signal controllers, explains the process of stimating commutation angle and motor speed. Motor position and speed are estimated based on measured currents and calculated voltages. The position and speed estimator is based on a current observer.
