摘　　要：为了对电机带载情况下的运行状态进行实时检测和评估,并对负载转矩波动进行有效补偿。介绍了适用于永磁同步电机负载状态观测的Luenberger观测器和各种不同形式的卡尔曼滤波器的详细设计方法。利用MATLAB/Simulink对所设计的观测器进行仿真建模,验证了所设计的状态观测器对负载转矩的补偿作用,对于提高系统的动态性能起到重要作用。This paper provides a detailed introduction to the design methods of Luenberger observers and various forms of Kalman filters in order to detect and evaluate the operating status of the motor under load in real-time,and effectively compensate for load torque fluctuations.This observer designed in this article is suitable for observing the load state of permanent magnet synchronous motors(PMSM).Then using MATLAB/Simulink to model and simulate the designed observer,the compensation effect of the designed state observer on load torque is verified.
