摘要：

A flux-weakening predictive control algorithm (FWPC) is proposed in this paper with the aim of extending Constant-Power Speed Range (CPSR) of Surface-Mounted Permanent Magnet Synchronous Machines (SPMs). The proposed FWPC is developed on the basis of an accurate SPM sampled-data model and consists of appropriately exploiting the DC-link voltage reserve that is generally set aside for dynamic purpose only. This goal is achieved by optimal and easy management of SPM operating constraints, i. e. current limitation and voltage saturation, without impairing SPM dynamic performances. The effectiveness of the proposed FWPC is verified through both simulation and experimental studies, which highlight the enhancement of SPM performances, especially in terms of CPSR extension.
