An investigation on the active control strategy for a high-speed pantograph using co-simulations

The article presents simulation results on the active control strategy for a railway pantograph to improve contact quality in pantograph-catenary interface. Three different approaches were investigated: nominal torque tuning, torque active control and combination of them-combined control approach. The first control scenario minimizes the pantograph nominal uplift force exerted on the catenary. The second approach is based on active pantograph toque control, employing the proportional-integral-derivative controller, to compensate actual contact force error. The last control scenario links the above-mentioned approaches. Promising results are obtained employing the co-simulation environment recently presented by the authors.
