| 摘 要： | 基于气隙磁密分析,建立了适用于间隙变化的直线感应电机动态数学模型以及推力和法向力表达式.针对直线感应电机的运行状况,分析了法向力的排斥力分量和吸引力分量的特点,提出了一种新颖的基于间接次级磁场定向的推力、法向力独立控制策略.仅仅依靠单边直线感应电动机,实现了静态和动态稳定悬浮、以及悬浮状态下的稳定牵引运动,并在一台直线感应电机模型车辆上进行了实验.实验结果表明,提出的解耦控制方案对直线感应电机的悬浮牵引联合控制具有良好的效果.

| Abstract: | Dynamic mathematic model with thrust and normal force of a single sided linear induction motor(SLIM) were established by flux distribution analysis,which was suitable for gap-length changing.Repulsive component and attractive component in normal force were analyzed according to SLIM's operation characteristics.A novel decoupling strategy was proposed to control independently thrust and normal force based on indirect flux orientation(IFO).The stable levitation and propulsion during levitation was realized in... |
