【 摘 要 】

This paper proposes an improved current decoupling method (ICDM) combined with forgetting factor recursive least square (FFRLS) of interior permanent magnet synchronous machine (IPMSM). The framework of the proposed model includes the complex vector decoupling module and the approximate voltage compensation module. The strategy of complex vector decoupling is extended to IPMSM, and the parameters setting of current loops is more flexible. Considering the inaccuracy of resistance measurement and parameter variation with temperature, FFRLS model is applied to update the voltage compensation online. The experiments results demonstrated that better dynamic response performance could be achieved using the proposed control method.
