摘要:
针对城市轨道交通中直线感应牵引电机效率较低问题,从控制角度研究电机的效率最优控制策略。建立直线感应牵引电机的数学模型,考虑边缘效应的影响将推力与磁通进行解耦,在分析法向力组成与特性的基础上,得出以初级电流为变量的数学表达式,结合最优化理论,考虑多个优化目标建立损耗最小函数,实现在满足水平推力的条件下对电机铜耗与法向力造成损耗的最优控制。仿真研究对比了采用普通矢量控制与本文所提方案的运行状况。仿真结果表明,直线感应牵引电机行程中恒速区段时间越长,损耗减少得越大,效率提高得越高。
Abstract:
Low efficiency of linear induction motor has been studied in the paper,and an efficiency optimail control stratery is proposed.Considering end effect,a math model of linear induction motor was made.Decoupling control of the force and flux was designed,aiming to nolinear and time-variantion of the flux,force and current for linear induction motor.Based on the analyses of the normal force,a primary-current math model was developed.Using optimal theory,we got the least loss function and optimal control.Compute...
