To simplify the control structure, improve transient performance and disturbance rejection ability of the permanent magnet synchronous motor (PMSM), a hybrid reaching law (HRL) based sliding mode control (SMC) and a time-varying nonlinear disturbance observer is proposed for the speed-current single...
