摘　　要：分析了感应电机在线效率最优控制的三种典型搜索算法,在对各种算法的复杂度、收敛速度以及节能效果等方面进行比较的基础上,提出了改进措施并进行了验证。讨论了动、稳态交替运行时效率控制策略的切换条件及励磁电流的控制方法,励磁电流指令的设定方式直接影响系统的动态特性。Three typical search algorithms for online efficiency optimization control of vector-controlled induction motor drive are analyzed. The complexity, convergence speed and energy-saving effect of these three algorithms are compared. Also, an improvement method is proposed and confirmed by simulations. Then, the changing conditions of efficiency control and the control method of excitation current are discussed when the performance of an induction motor is changed between transient and steady state.
