摘要: 针对弓网耦合问题,提出了弓网系统的半主动控制策略。根据建立的弓网模型和接触力历史数据,利用预测控制技术,预测下一时刻接触力;将预测值与理论值对比计算误差,MPC控制器将计算结果输出给电流变阻尼器;由电流变阻尼器提供接触力的控制输入变化量,使得实际值接近于理论值。实验结果表明:半主动控制策略在弓网系统的应用,能有效提高弓网耦合质量,抑制离线电弧的发生,优化受流质量。

Abstract: For the pantograph catenary coupling problem, the semi-active control strategy of pantograph catenary system was proposed. According to the established pantograph catenary model and the contact force history data, it used the MPC prediction technique to predict the next moment of contact force. The predicted value and the theoretical value error were calculated, and the MPC controller output the calculated results to the ER damper. The change of the control input of the contact force was provided by the current damper, which made the actual value close to the theoretical value. Experimental results show that the semi-active control strategy in the application of the pantograph catenary system, effectively improve the coupling quality of pantograph and catenary, restrain the occurrence of off-line arc, and optimize the quality of the flow.

Key words: pantograph-catenary system, semi-active control, electro-rheological damper, MPC
