自适应Backstepping在永磁同步电动机速度跟踪控制中的应用

Speed Tracking Control of Permanent Magent Synchronous Motor with Adaptive Backstepping

把自适应Backstepping应用于具有不确定参数的永磁同步电动机速度跟踪控制中,系统设计实现了定子电阻、粘滞系数和负载的实时估计,能够在系统参数发生变化时保证控制系统的快速速度跟踪。并证明了系统跟踪误差和参数的全局一致收敛。最后通过Matlab仿真验证了系统设计的有效性和可行性。

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.
