To enhance the parameter robustness of the current decoupling controller of a high-speed permanent magnet synchronous motor (HSPMSM), first, a current decoupling controller with high parameter robustness is proposed. Then, a parameter optimization design method is put forward. Based on the zero-pole cancellation principle, the proposed method directly designs the current decoupling controller in the discrete-domain, which can effectively overcome the delay effect of the digital control system under low carrier ratio conditions, thus greatly improving the parameter robustness of the controller. Finally, experimental results based on the HSPMSM verified the effectiveness of the proposed method.
