基于高阶快速终端滑模负载转矩观测器的感应电机驱动抗扰速度控制

Speed loop is the key factor affecting the performance of induction machine (IM) drives. Conventionally, the proportional integral (PI) controller is applied for its simple implementation and static-errorless; however, its performance degrades apparently under sudden external load torque changes. To address this problem, this paper presents a nonlinear control strategy, combining the conventional ...
