Abstract：The performance of the finite-control-set model predictive control (FCS-MPC) depends on the accuracy of model parameters. Therefore, this paper proposed a PID-type cost function for the FCS-MPC in the current control of the permanent magnet synchronous motors, including the integral cost term to eliminate the steady-state current error and the differential cost term to reduce the root-mean-square current error. In the concept of the PID-type cost function, the traditional reference-tracking cost can be categorized as a proportional cost. Experimental results show that the FCS-MPC current control with the PID-type cost function can reduce the steady-state current error to zero and suppress the current ripple in a wide parameter range. Therefore, the parameter independency of the FCS-MPC can be improved while retaining the advantage of fast dynamic response of the FCS-MPC.
