ACTIVE CONTROL OF A HIGH-SPEED PANTOGRAPH

The design and performance of an active controller for a pantograph wh ich collects current for a high-speed train are considered. A dynamic model of the pantograph/catenary system is described and control objec tives are established A design which incorporates a frame-actuated con troller and requires only a single measurement is described Over an ar ray of train speeds, the contact force variation with the actively con trolled pantograph is 50 percent less than for the equivalent passive pantograph system.
