Abstract： Traditional three-vector model predictive current control for permanent magnet synchronous motors faces challenges such as high computational complexity and excessive control delay. To resolve these limitations，a model predictive current control strategy based on ideal voltage vector position was proposed.First，the first optimal voltage vector was selected through online optimization based on vector synthesis and sector division principles.Additional voltage vectors were then introduced to subdivide the original sector and refine the selection process. The second optimal voltage vector was determined by combining the subdivided sector with the ideal voltage vector position. Finally，the zero vector was chosen according to the minimum switching transitions principle. To further reduce computational effort，the active time of selected voltage vectors was calculated using the minimum d-q axis component error principle. The cost function structure was optimized according to motor operating states to ensure robust control performance across varying conditions. Simulation and experimental results demonstrate that the proposed algorithm reduces voltage vector optimization iterations，controllr computation time，and control delay. It also improves system response speed， enhances tracking capability， minimizes current and speed ripples， and achieves good dynamic response and steady-state performance.
