| 摘 要： | 对接触网的刚度进行非线性最小二乘拟合,建立了弓网系统非线性模型,采用微分几何理论对弓网间接触力波动进行控制,提出一种输出-干扰解耦方法,通过适当的非线性坐标变换,将非线性系统转化为线性系统,并施以最优控制,仿真结果表明,控制效果良好.

| Abstract: | The catenary stiffness is fitted by nonlinear least square method and a nonlinear dynamical model of catenary/pantograph system is established in this paper. Output_perturbance uncoupled method educed from differential geometry is first used in the high speed pantograph_catenary system. The nonlinear model is transferred to a simple linear system by a proper coordinate transform and the optimal control strategy is applied. The simulation results show that the controller is effective. |
