为了解决永磁同步电机在多工况下转速易受到内外扰动的影响,提出一种基于延迟补偿的并行线性自抗扰控制策略.针对永磁同步电机可能受到信号处理、逆变器响应等因素从而引入的外部时滞效应的问题,引入Smith预估器与自抗扰控制相结合,使控制系统更加精确、快速地响应内部参数变化和外部扰动.同时,针对线性自抗扰控制器(LADRC)在有限带宽内其抗扰性能较差的问题,设计了并行线性自抗扰控制器,在保持其带宽不变与参数易于整定的同时,有效提高其抗扰动能力.最后,对自抗扰控制器的稳定性进行了分析,并在此基础上进行了参数设计与扰动性能分析.仿真与实验结果表明,所提算法相比LADRC在电机受到速度阶跃、...

To address the issues of speed susceptibility to internal and external disturbances under various operating conditions in permanent magnet synchronous motor(PMSM),a parallel linear active disturbance rejection control(PLADRC)strategy based on delay compensation is proposed.Aiming at the problem that PMSM may be subject to the external time lag effect introduced by signal processing,inverter response,and other factors,the Smith predictor is introduced in combination with the active disturbance rejection control(ADRC)to make the control system re...
