Decoupling of vector control and parameter setting for induction motor

Asynchronous motor is a multi-variables, nonlinear, strong coupling and time-varying system, in order to eliminate the coupling impact of the stator current, design the current decoupling controller to achieve the stator current torque component and the excitation component nonlinear decoupling by non-linear compensation method, it make PI controller parameters setting simplified. According to this method, design the parameters of the current PI regulator and the speed PI regulator, Experiments proved this controller has good dynamic performance.
