摘 要：This paper presents a sensorless control strategy for the surface-mounted permanent magnet synchronous motors（SPMSMs） with a sliding mode controller（SMC）.To extract accurate rotor position from the back electromotive force（EMF） of the SPMSM,a tangent function-based phase-locked loop（PLL） is *** extra tuning of parameters,the position estimation scheme manages to provide accurate rotor position under both forward and reverse rotational *** to conventional sliding mode control approach,the proposed SMC adopts a nonlinear reaching law,which helps the controller to simultaneously achieve faster reaching time and lower chattering *** of the proposed control strategy is verified by simulation results.
