高速受电弓最优主动与半主动控制比较

The comparison between optimal active control and semi-active control of the high-speed pantograph

根据研究需要,建立了弓网二元模型,分析了主动控制与半主动控制原理,建立了各自的动力学方程,建立了两种控制方式下的Simulink仿真模型,选取了合适的弓网参数,对不同速度下的弓网接触力和接触力指标进行对比,分析不同控制方式对受流质量的作用效果。

The pantograph-catenary model was built for research. The control principles of the optimal control and semi-active control were stated, then the kinetic equation and the simulation model were built for each. Based on the established control models and simulation, the proper parameters were selected and the influences of active control and semi-active control to quality of current collection of the pantograph-catenary system are analyzed, which concluded from the comparison of the contact force and index of the pantograph-catenary in the different speeds.
