Abstract The design of an Active Disturbance Rejection Controller for the Brushless DC motor (BLDC) that compensates load torque variations in the rotor shaft without the measurement of the rotor shaft speed is presented. The reconstruction of the unknown load and motor speed is accomplished by the combination of a generalized Proportional Integral Control (PI) and a Luenberger observer, while the stator current regulation is designed around a passivity based controller. Using parameters of a commercial motor designed for a small electric vehicle under different driving conditions, numerical simulation results are included that validate the effectiveness of the proposed scheme both in terms of transient response to changes in set points and in tracking variable speed references.

用于汽车应用的具有可变转矩负载的无刷直流电机的稳健控制

摘要 提出了一种用于无刷直流电机 (BLDC) 的有源抗扰控制器的设计，该控制器无需测量转子轴速度即可补偿转子轴中的负载扭矩变化。未知负载和电机速度的重建是通过广义比例积分控制 (PI) 和 Luenberger 观测器的组合完成的，而定子电流调节是围绕基于无源的控制器设计的。使用为不同驾驶条件下的小型电动汽车设计的商用电机的参数，包括数值模拟结果，验证了所提出方案在对设定点变化的瞬态响应和跟踪变速参考方面的有效性。
