中文摘要
      针对三相永磁同步电机(PMSM)驱动系统, 基于滑模变结构模型参考自适应(MRAS)技术, 提出了一种新颖的无速度传感器模型预测转矩控制(MPTC)策略. 采用滑模变结构模型参考自适应方法构造电机转速观测器, 以改善速度估计精度并提高系统鲁棒性; 利用模型预测转矩控制策略, 以达到减小转矩和磁链纹波并提高系统控制性能的目的. 仿真结果表明: 就滑模MRAS观测器与MRAS观测器比较而言, 基于前者的PMSM无速度传感器MPTC系统比基于后者的PMSM无速度传感器MPTC系统具有较强的鲁棒性和更好的动态性能; 就MPTC与直接转矩控制(DTC)和磁场定向控制(FOC)比较而言, 采用前者策略的无速度传感器电机驱动系统能够降低逆变器开关频率、减少相电流总谐波失真(THD), 从而提高系统可靠性.
英文摘要
      A novel sensorless model predictive torque control (MPTC) strategy is proposed for the three-phase permanent magnet synchronous motor (PMSM) drive system with sliding-mode model reference adaptive system (MRAS) observer. Making use of techniques of MRAS and sliding-mode, we design a sliding-mode MRAS observer to improve the estimated speed accuracy and enhance the system robustness. In order to reduce the torque and flux ripples and improve the control performance, we employ the MPTC strategy in the approach. Numerical simulation validates the feasibility and effectiveness of the proposed scheme. In comparison with the sensorless MPTC involving MRAS observer, the proposed MPTC with sliding-model MRAS observer provides stronger robustness and achieves satisfactory torque and speed control. Meanwhile, comparing to the sensorless direct torque control (DTC) and sensorless field-oriented control (FOC), we find the proposed sensorless MPTC reduces the average inverter switching frequency and decreases the total harmonic distortion (THD) of the phase current, and thus improves the industrial reliability.
