摘要
永磁同步电机(PMSM)在某些参数及工作条件下会出现混沌现象,这将严重威胁整个系统的稳定运行,为了确保电机的安全运行,必须通过控制消除电机混沌现象。本文首先通过时间尺度变换和线性仿射变换把永磁同步电机(PMSM)的动态方程变换成类Lorenz的混沌模型,验证了永磁同步电机(PMSM)混沌现象的存在。随后介绍了自抗扰控制器各个组成部分,并且设计了针对永磁同步电机(PMSM)混沌现象的自抗扰控制器(ADRC)对电机运行过程中出现的混沌现象进行控制。最后仿真结果验证了自抗扰控制器(ADRC)对永磁同步电机(PMSM)混沌现象具有良好的控制效果,有很强的抗扰能力,可以保证电机运行的稳定性和可靠性。此外,该算法实现简单,极具实用价值,为永磁同步电机(PMSM)中混沌现象控制提供了有价值的参考。
Chaos phenomenon in permanent magnet synchronous motor(PMSM) running will appear with some special parameters or under certain working conditions and it is a serious threat to the stability of the whole system.A controller should be designed to eliminate the chaos to ensure the safe operation of the motor.To address this issue,this in this paper chaos mathematical model of permanent magnet synchronous motor(PMSM) is deduced by time scale transformation and linear radiation transformation,and it has verified the existence of chaotic phenomena in the permanent magnet synchronous motor(PMSM).Then the paper describes the various components of the ADRC controller and an ADRC controller is designed for PMSM chaotic phenomena to control the chaos phenomenon in PMSM.Finally,the simulation results demonstrate the effectiveness of the ADRC controller.The ADRC controller has strong anti-interference ability and can guarantee the stability of operation and reliability.In addition,the ADRC is simple and has highly practical value.The ideal results also provide a valuable reference for the control of chaotic phenomena in the permanent magnet synchronous motor(PMSM).
