Abstract
In the past 25 years, many researchers have investigated the problem of optimum current pick-up in high speed running railways. There is the re- quirement of maintaining almost constant the contact force between pan- tograph and catenary, thus avoiding losses of contact involving mechanical, electric and electromagnetic negative consequences, such as: excessive wear, insufficient current pick-up, high EMI. One of the proposed solutions to this nroblem is to design servo-actuated pantographs and regulate relevant vari- ables, such as the contact force, during operation. Since 1993, researchers of the University of Florence have proposed solutions for the placement of sen- sors and actuators on existing pantographs for high speed operation as well as their contro
