摘要：

为了提高三相四开关逆变器永磁同步电机(PMSM)控制系统的性能,采用滑模控制方法,提出一种有限控制集模型预测控制(FCS-MPC)策略,并设计可以无抖振、单调收敛的滑模转速调节器.所设计的控制系统能够保证PMSM系统可靠稳定地运行,可抑制PMSM的电磁转矩脉动,改善三相定子电流波形效果,具备良好的转速跟随性能.仿真结果表明,与常规FCS-MPC方法相比,滑模转速调节器可以使电机加载时的转速跌落更小,并且转速能够更快恢复至参考值.所提出的FCS-MPC策略可以明显减小PMSM转矩脉动，降低三相定子电流总谐波失真(THD)值.当系统参数发生变化时,PMSM系统仍可平稳运行,三相定子电流能够保持良好的平衡性.
Abstract:
A finite-control-set model predictive control (FCS-MPC) strategy was proposed for permanent magnet synchronous motor (PMSM) system driven by three-phase four-switch inverter, based on sliding mode control method, to improve the operation performance of control system. A speed regulator was designed using the sliding mode control method, with no chattering and monotone convergence. The designed control system enabled PMSM system to run with favorable reliability and stability. The proposed control method was helpful for the electromagnetic torque reduction, the quality improvement of three phase stator currents, and the better speed tracing performance. Compared with the conventional FCS-MPC strategy, numerical simulation results illustrate that the designed speed regulator based on sliding mode control can make the motor speed have a smaller decline and recover to reference value more quickly and accurately after the motor load increase. The proposed FCS-MPC can obviously reduce the torque ripple of PMSM and decrease the total harmonic distortion (THD) value of three phase stator currents. The PMSM system can still guarantee stable operation with respect to the system parameter variation, as well as a satisfactory balance behavior of three phase stator currents in this condition.
