摘要
设计一种新的适用于永磁同步电机(PMSM)的非线性反步控制器,该控制器可以获得较好的速度跟踪。在设计过程中,系统的稳定性是由Lyapunov稳定性理论来保证的。由于加入了积分环节,性能得到明显改善,使PMSM驱动系统的速度控制具有较好的瞬态特性,并且解决了拒绝干扰注入的难题,提高了系统高效的稳态特性。仿真结果的比较分析证明了该控制方法的可行性。
A new nonlinear backstepping controller suitable for PMSM was designed to obtain good speed tracking. Inthe design process, the stability of the system was guaranteed by the Lyapunov stability theory. Joined integral part in thecontroller, the performance was significantly improved. This method for speed control of PMSM drive system with a bettertransient characteristics solved the problem of refusing to inject interference and improved the system efficient the steadystate characteristics. Some simulation results were compared and analyzed to prove the feasibility of this method of control.
