Robust predictive current control of induction motors based on linear extended state observer

Model predictive current control can achieve fast dynamic response and satisfactory steady-state performance for induction motor (IM) drives. However, many parameters are required to implement the algorithm. Consequently, if used in controller not accurate, may deteriorate. In this paper, a new robust is proposed improve robustness against parameter mismatches. The method employs an ultra-local model replace mathematical of IM. Additionally, performance, linear extended state observer developed disturbance estimation. Experimental tests confirm that tracking still be obtained although accurately set controller.
