The energy optimization design of the safety door's control system in the urban light rail transit line

Abstract

This paper presents an energy optimization method of the safety door's motion control. Considering the multiple factors that affect the safety door's energy consumption, we establish an objective function and a constraint equation, and propose an energy optimization method based on Sequential Quadratic Programming (SQP) algorithm. The controllable curve of the instantaneous linear velocity for the safety door based on the optimization design can be finally obtained. This method has been proved to be effective by experiments. © 2007 Springer-Verlag Berlin Heidelberg.
