| 摘 要： | 磁悬浮列车控制系统性能直接影响到磁浮列车的稳定性、安全性,由于电磁铁模型本身的不稳定性和非线性,悬浮系统必须选择合适的控制方式才能使其稳定工作.为消除扰动对磁悬浮列车悬浮系统的影响,在线性近似模型基础上提出一种前馈-反馈复合控制结构,利用PI控制器消除稳态误差,利用前馈控制抵消扰动对系统的影响.采用MATLAB对系统进...

| Abstract: | It was expounded that the suspension controlling system of the magnetic levitation train was very important for its safety and stability.Because the solenoid model was unstable and nonlinear,a proper controlling mode should be selected for the suspension system to be able to work stably.In order to eliminate the influence of disturbance on levitation system,a feedforward-feedback compound control structure was presented based on the approximate linear model.A PI feedback controller was used to eliminate ste... |
