| 摘 要： | 针对含未知参数的永磁同步电机(PMSM)系统,研究其参数稳定性和自适应控制问题.首先,分析了参数变化对PMSM系统平衡点的影响.然后,通过设计自适应控制器使得闭环系统具有耗散Hamiltonian结构,使闭环系统的能量分布随着未知参数的漂移而自动的改变,且能量函数总在未知参数对应的平衡点处取得极小值,从而实现自适应参数...

| Abstract: | This paper studies parametric stability and adaptive control of permanent magnet synchronous motors(PMSM) with unknown parameters.First,the impact of the parameters on the equilibrium location is investigated for PMSM system.Then,an adaptive controller is designed to transfer closed-loop system into dissipative Hamiltonian form.The energy distribution of closed-loop system can change automatically with the shift of unknown parameters.The energy function always achieves minimal value in different equilibrium... |
