摘要
针对永磁同步电动机混沌系统的有限时间稳定控制问题,提出了一种动态有源补偿的主动控制方法,使闭环系统达到近似有限时间稳定控制。首先对永磁同步电动机的数学模型进行分岔和混沌分析,判断系统进入混沌状态的条件。然后针对系统存在的混沌,通过引入奇异摄动理论,详细地分析了闭环系统近似有限时间稳定性,提出主动控制方法,通过仿真和实验验证该方法可以有效地解决系统的不确定性。
Aiming at the finite time stability control problem of the chaos system of permanent magnet synchronous motor,this paper proposed an active control method of dynamic active compensation,which made the closed-loop system reach the approxi-mate finite time stability control.Firstly,it made bifurcation and chaos study the mathematical model of permanent magnet synchronous motor to judge the condition of the system into chaotic state.Then,based on the chaos of the system,this paper analysed the approximate finite time stability of the closed-loop system in detail by introducing the singular perturbation theory and put forward the active control method.The simulation and experimental results show that the method can effectively solve the system’s uncertainty.
