摘要

The decoupling current controller with high dynamic performance is required in the high speed regulation of a vector controlled PMSM system. In this paper, the “relative gain” is introduced to analyze the coupling phenomena of PMSM current loop firstly. Then, three different decoupling schemes based on internal model control, feed-forward compensation and diagonal compensation are elaborated. By adopting these various decoupling control schemes, the current regulation can achieve high performance. The correctness and feasibility of the decoupling methods are verified by simulation and experimental results.
