N2 - To enhance the performance of permanent magnet synchronous motor drive, a sensorless direct torque control (DTC) scheme based on adaptive backstepping control is proposed to control the torque and stator flux linkage, which use five-order permanent magnet synchronous motor (PMSM) dynamic model in the stationary frame with stator currents, rotor flux linkage and rotor speed. In the proposed scheme, the reference voltages were obtained by a designed model reference adaptive backstepping controller to drive PMSM. By combining the adaptive control, the system possesses the advantages of good transient performance and the robustness to the parametric uncertainties and load torque disturbance. Moreover, a adaptive flux linkage observer is designed to provide the simultaneous estimation of the rotor flux linkage and speed. The simulation results show that the designed controller can guarantee the globally asymptotically stability of system, and the system achieve excellent speed estimation and speed tracking performance.
