永磁同步电机的自适应反步滑模变结构的混沌控制

Chaotic control of PMSM system with adaptive backstepping sliding mode law

永磁同步电机的动力学特性表明在一定的条件下PMSM会呈现混沌特性行为.为了控制不良的混沌振动,设计了一个基于自适应反步法的滑模变结构非线性控制器.M atlab数字仿真表明,基于自适应反步法的滑模变结构控制器具有健全的控制性能,它能够消除混沌现象,并能把系统的跟踪误差和参数变化迅速地以指数规律收敛到零,使得系统具有较强的抗干扰性.

The dynamics of a permanent magnet synchronous machine(PMSM) shows that under certain conditions,the PMSM is experiencing chaotic behavior.To control these undesirable chaotic oscillations,a nonlinear controller based on the adaptive backstepping sliding mode law was designed.The result of simulation demonstrated that the sliding model controller based on the adaptive backstepping had healthy control performance and could eliminate the undesirable chaotic oscillations.The tracking error and parameters devia...
