This paper presents a gain tuning method of the load torque compensator for direct speed control based on finite control set model predictive control (FCS‐MPC). In this method, the transfer function between the error in predicted speed and the load torque is constructed and used for gain parameter tuning of a load torque observer‐based prediction error correction. By using the proposed method, the stability and the responsiveness of FCS‐MPC with a load torque compensation can be improved without a fully simulating the electric drive systems and experiments. The simulation and experimental results obtained with a permanent magnet synchronous motor, fed by a two‐level three‐phase voltage source inverter, show that the tracking performance of the direct speed control tuned by the proposed method was excellent under load torque conditions. © 2020 Institute of Electrical Engineers of Japan.

带有负载转矩补偿的有限控制模型预测速度控制

本文提出了一种基于有限控制集模型预测控制（FCS‐MPC）的直接速度控制负载转矩补偿器的增益调整方法。在这种方法中，构造了预测速度误差与负载转矩之间的传递函数，并将其用于基于负载转矩观测器的预测误差校正的增益参数调整。通过使用所提出的方法，可以在不完全模拟电驱动系统和实验的情况下提高带有负载转矩补偿的FCS-MPC的稳定性和响应性。永磁同步电动机由两级三相电压源逆变器馈电的仿真和实验结果表明，在负载转矩条件下，该方法所调节的直接速度控制的跟踪性能非常好。©2020日本电气工程师学会。由Wiley Periodicals LLC发布。
