摘要
针对无传感器永磁同步电动机转子位置和转速难以检测的问题,重点描述了一种基于滑模电流观测器估算转子位置和速度信息的解决方案,并设计和开发了基于电机专用控制芯片的控制器。实验结果表明该方案可以有效地实现转子位置的检测及电流换相控制,具有一定的工程应用价值。
To deal with the problems that the rotor position and speed are hard to detect, a solution based on the sliding mode current observer was presented to estimate the rotor＇s position and velocity, and a controller was designed and devel- oped based on DSP. Experimental result confirms that the proposed solution not only can precisely detect the rotor＇s position and better control of current commutation, but also has practical value in use.
