自调试期间死区效应电压误差模型的双参数辨识方法

An identification method is presented for the arctan two-parameter model, which describes the deadtime effect voltage error of permanent magnet synchronous motor drives' three-phase voltage source inverter (VSI) during self-commission. In this method, the motor maintains a standstill during the whole identification process. First, a disturbance observer is used to improve the tracking performance ...
