Design and Implementation of Adaptive Backstepping Speed Control for Permanent Magnet Synchronous Motor

A nonlinear speed controller for permanent magnet synchronous motor based on adaptive backstepping control is designed, which used second-order filter to smooth the speed reference. By combining the adaptive control, the uncertain parameter and load torque is estimated when the nonlinear speed controller is designed. A simulation model for a permanent magnet synchronous motor speed servo system using the proposed nonlinear controller was built. A DSP-based real-time experimental research was carried out. The simulation and experimental results show that the designed controller can guarantee the globally asymptotically stability of system, and the PMSM servo system achieved excellent tracking performance, and is robust to uncertain parameters and load torque disturbance
