中文摘要
      针对三相四开关逆变器驱动永磁同步电机(PMSM)系统, 基于扩张状态观测器(ESO)技术, 提出了无速度传 感器的自抗扰模型预测转矩控制(ADRMPTC)策略. 建立了三相四开关逆变器驱动PMSM系统的数学模型; 采 用ESO技术构造了PMSM系统转速观测器, 以实现对转速快速准确地实时估计; 用自抗扰控制器(ADRC)作为系统 的转速调节器, 以提高系统的鲁棒性; 利用模型预测转矩控制(MPTC)方法, 以达到减小转矩和磁链脉动的目的. 所 设计基于ESO的无速度传感器ADRMPTC策略能够使三相四开关逆变器驱动的PMSM系统可靠稳定运行, 达到满 意的转矩和转速控制效果. 与基于PI的MPTC策略相比, 本文控制策略使PMSM系统不仅具有良好的动态性能, 而且 具有较强的抗负载干扰能力. 仿真结果验证了所提方法的正确性和有效性.
英文摘要
      A novel sensorless active disturbance rejection model predictive torque control (ADRMPTC) strategy is developed for permanent magnet synchronous motors (PMSMs) fed by three-phase four-switch inverters, an after-faulttopology for a fault-tolerant three-phase six-switch inverter. Firstly the mathematical model of a PMSM fed by a three-phase four-switch inverter is built. Secondly by the use of technique of extended state observer (ESO), a sensorless estimator is constructed to realize rapid and accurate speed identification. Thirdly an active disturbance rejection controller (ADRC), acting as speed regulator, is designed to realize disturbance estimation and disturbance compensation for the purpose of enhancing robustness. Finally a model predictive torque controller (MPTC) is designed in order to reduce the torque and flux ripples. The resultant ESO-based sensorless ADRMPTC strategy for PMSMs fed by an unhealthy inverter has fault-tolerant ability with dynamical performance very close to the PMSMs fed by a healthy inverter. On the other hand, compared with PI-based MPTC strategy, the ADRMPTC strategy enables the PMSMs to possess better command-following characteristics and stronger robustness in the presence of variations of reference speed and load torque. The simulation results validate the feasibility and effectiveness of the proposed scheme.
