Abstract: A current mirror fault-tolerant control (CMFC) strategy is proposed to solve the problems of high parameter dependence and poor robustness in the dual-mover current sensorless control. This strategy uses only the single-mover phase current sensor to complete the control of the two cascade linkage movers. In the dual-mover system, mover 1 is a normal mover, which uses traditional finite control set-model predictive control (FCS-MPC) to complete current tracking control. Meanwhile, mover 2 is a faulty mover, and all current sensors have failed. The CMFC control takes the virtual current of movers 2 and 1 as the input of the FCS-MPC controller and completes the current tracking control. The actual current tracking of the two movers is realized by the mirror image principle by completing the virtual current tracking of the two movers. Theoretical analysis and simulation experiments prove that the CMFC control can realize the stable control of the actual current of the mover 2, demonstrating high robustness.
