<![CDATA[Dynamic interaction of pantograph and catenary is one of the most important factors affecting the safe and reliable operation of high-speed trains. In order to improve the quality of contact between pantograph and catenary, it is necessary to study the active control strategy of pantographs. In this dissertation, according to dynamic characteristics of pantograph and catenary, applying fuzzy control principle, the author designed a fuzzy controller of pantograph.Comparing with the situation without fuzzy control circuit, it is the result that standard deviation of contact force with a fuzzy control circuit is smaller than it without control, 39.5% off at 200km/h, 21.2% off at 300km/h, which indicate that using a pantograph with a fuzzy controller can improve the contact quality between pantograph and catenary effectively.]]>
