Robust Active Vibration Control for Rail Vehicle Pantograph

The delivery of electricity to a light rail transit (LRT) vehicle’s pantograph is essential to the pantograph’s function. In this paper, the author describes a method for improving the contact between the pantograph and contact wire in terms of a control evolutionary algorithm (EA) to mitigate the effects of vibration on power delivery. Using a linear quadratic regulator, a stabilizing control with time varying contact force can be established. Optimizing the pantograph contact is accomplished using a Pareto set with variable weights for suspension. This method is ideal for such applications as it can gain optimal contact effect, improve handling quality, and provide robust stability. Numerical verifications and comparisons with other design types are presented, with the proposed method outperforming the others.
