摘　　要：针对传统永磁同步电机直接转矩控制中电机效率优化方法存在计算复杂、影响电机稳态性能等缺点,提出基于在线磁链观测器的最小损耗算法。所提算法充分考虑电机本体参数的变化特性,以直接转矩系统中参考磁链为研究对象,建立电机动态最小损耗模型。通过仿真和实验验证了所提模型算法的有效性,实现了运行效率的提升,保证了电机运行的动、稳态性能。Traditional PMSM direct torque control of the motor efficiency optimization method has computational complexity,which affects the motor steady-state performance and other shortcomings. The algorithm based on the minimum loss of dynamic flux observer was proposed. This algorithm fully considered the characteristics of the motor body parameters change to the system and took the direct torque reference flux as the research object,the dynamic motor model of minimum loss was established. Simulation and experimental results verify the validity of the proposed model algorithm which achieves the efficiency improvement,ensures the steady state and dynamic performance of the motor running.
