【Abstract】 Adaptive Backstepping control is applied to the speed tracking control of permanent magnet synchronous motor (PMSM) with uncertain parameters. The system design can estimate stator resistance, friction coefficient and load with real time. At mean time, the system can remain its good performance when system parameters deviate from normal values. Global ultimate attractiveness of system tracking error and parameters is also proved. At last Matlab simulation is given, which proves the efficiency and feasibility of system design.更多还原
