摘要
针对高精度的伺服系统,考虑永磁同步电动机实际运行过程中,电机的定子电阻、粘滞磨擦系数及负载转矩的变化,必然影响到系统的伺服精度。因此,提出了自适应与反推控制相结合的控制策略,通过推导,它不但能够实现永磁同步电动机系统的完全解耦,并且能够有效抑制系统参数变化对系统速度跟踪伺服性能的影响,使系统具有很强的鲁棒性。通过仿真,验证了自适应反推控制策略的有效性和可行性。
In view of the high accurate servosystem, the changes in the stator resistance, the adhesive friction coefficient and the load moment affect inevitably the precision of the system servo in the actual operating process of PMSM. Therefore, proposes a control strategy which combines adaptive with backstepping control. Through the inferential reasoning, it not only can realize the complete decoupling of PMSM system, but also can effectively suppress the influence of the system parameter change on the system velocity tracking servo performance to make the system very strong robustness. Through the simulation, it is confirmed that the validity and the feasibility of the control strategy which combines adaptive with backstepping control.
