永磁同步电机直接转矩控制在线效率优化方法
Online Efficiency Optimization Method Based on Direct Torque Control of PMSM
摘要
Abstract
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.关键词
