Robust predictive current control of induction motors based on linear extended state observer [PDF]
Chinese Journal of Electrical Engineering, 2021 Model predictive current control can achieve fast dynamic response and satisfactory steady-state performance for induction motor (IM) drives. However, many motor parameters are required to implement the control algorithm. Consequently, if the motor parameters used in the controller are not accurate, the performance may deteriorate. In this paper, a new
