摘要: 针对永磁同步电机转速控制系统中采用滑模控制存在抖振现象以及自抗扰控制轨迹跟踪准确性能较差等问题,提出一种基于固定时间收敛的非奇异快速终端滑模自抗扰复合控制器。建立了考虑外部扰动的永磁同步电机动力学模型,为减弱系统抖振现象、增强系统跟踪性能及抗扰性能,基于自抗扰控制架构,引入了固定时间扩张状态观测器和固定时间非奇异快速终端滑模控制器,并进行了稳定性分析。通过仿真对比,验证了该复合控制器的有效性及优越性。

Abstract: There was buffeting in sliding mode control (SMC) and poor tracking accuracy in active disturbance rejection control (ADRC) in the speed control system of permanent magnet synchronous motor (PMSM), a fixed-time nonsingular fast terminal sliding mode (FNFTSMC) and ADRC composite controllerwas proposed.The dynamic model of PMSM considering external disturbances was established.In order to reduce buffeting, enhance tracking accuracy and anti-jamming performance,fixed-time expansion state observer (FESO) and FNFTSMCwere introduced based on ADRC.The stability analysis was carried out.The effectiveness and superiority of the proposed controller were verified by MATLAB simulation.

Key words: permanent magnet synchronous motor(PMSM), fixed-time, nonsingular fast terminal(NFT), sliding mode control (SMC), active disturbance rejection controller(ADRC), extended state observer(ESO)
