The load torque of 0.36 N·m acted as the disturbance on the load side.The dynamic response of the speed and q-axis current are shown in Figs 15-17.It is evident that the proposed ASMC+ESO method has a better anti-disturbance capability than the PI and ASMC methods.Compared to the PI and ASMC methods,the ASMC+ESO method gives a smaller fluctuation in speed and a smaller overshoot in q-axis current.In addition,the speed and q-axis current are guaranteed to be restored to their original values much faster.The details of the experimental results are listed in Table 3,which demonstrate that the proposed speed control method enhances the system performance in the presence of load disturbance and alleviates sliding mode chattering effectively.
