| 摘 要： | 为提高感应电机(IM)运行效率,在考虑铁损数学模型的基础上,给出了高低转速工况下的电压电流约束条件,将保证损耗最小的最优转子磁链给定转化为在约束条件下的目标函数求最小值问题。通过定义广义Lagrange函数,结合Kuhn-Tucker定理分别求解出恒转矩区和恒功率区约束条件下的最优转子磁链给定,保证IM在整个工作范围内的效率最大化。试验结果验证了该方法的有效性。

| Abstract: | In order to improved the efficiency of induction motor (IM), on the basis of considering the iron loss mathematical model, voltage and current constraints at high and low speed conditions were given. The given of the optimal rotor flux linkage to ensure the smallest loss was transformed into the minimization of the objective function under constraint conditions. The generalized Lagrange function was defined, and the Kuhn-Tucker theorem was used to solve the optimal rotor flux linkage under constant torque region and constant power region, then IM efficiency was maximized in the entire working range. Simulation results verified the effectiveness of the proposed method. |
