摘要
使用数字信号控制器dsPIC6010A,以软件方式实现永磁同步电动机的无传感器磁场定向控制,重点描述了电机位置和速度的估算过程。位置和速度值是根据测量电流和计算电压得到的,位置和速度估算器基于电流观测器而构建。
A software - based implementation of sensorless field oriented control for permanent magnet synchronous motors using digital signal controllers dsPIC6010A was illustrated ,the process of stimating commutation angle and motor speed were explained. Motor position and speed were estimated based on measured currents and calculated voltages. The position and speed estimator were based on a current observer.
