Abstract:To address the issue of the heavy computational burden in traditional model predictive torque control (MPTC) for permanent magnet synchronous motors (PMSMs), a simplified MPTC strategy was proposed. By analyzing the utilization rates of basic voltage vectors in different stator flux linkage sectors, voltage vectors with lower utilization rates were discarded, thereby reducing the number of candidate voltage vectors. Additionally, the utilization of the zero-voltage vector under different absolute values of torque error was analyzed. When the torque error was small, the zero-voltage vector was directly applied; when the torque error was large, the zero-voltage vector was discarded, reducing the maximum number of candidate voltage vectors to four. Furthermore, a flux linkage error constraint was added to the cost function, effectively reducing flux linkage ripple. Simulation results showed that, compared to traditional MPTC, the proposed simplified control strategy effectively reduced the number of MPTC travers
