Modeling and Simulation for Adaptive Backstepping Control of PMSM

A nonlinear speed controller for permanent magnet synchronous motor based on adaptive backstepping control was designed, which uses second-order filter to smooth the speed reference. The uncertain parameter and load torque were estimated. A simulation model for the permanent magnet synchronous motor speed servo system using the proposed nonlinear controller was built. Thc simulation results show that the controller can guarantee thc global asymptotical stability of the system, and thc PMSM scrvo system achieves cxcellent tracking performance, and is robust to uncertain parameters and load torque disturbance.
