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.
The stiffness of the catenary is subjected to nonlinear least square fitting, and the nonlinear model of the catenary system is established. The differential geometric theory is used to control the contact force fluctuation between the cots. A decoupling method of output disturbance is proposed, Linear coordinate transformation, the nonlinear system is transformed into a linear system, and the optimal control, the simulation results show that the control effect is good.
