基于变结构扩展滑模观测器的永磁同步电机负载转矩与转动惯量同步辨识

In this article, a variable structure sliding mode observer (VS-SMO) for load torque observation is designed by adding a decoupling term to the structure of the traditional sliding mode observer. The VS-SMO can remove the coupling relationship between the parameter to be estimated and the derivative of the estimated speed error, as well as the chattering signal in the estimated load torque. Then, ...
