Model development and parameter investigation of a column-type electric power steering system

摘要

In this paper, the performance of a column-type electric power steering (EPS) system and vehicle has been studied and a detailed mathematical model for the system has been established. Based on the mathematic model of the optimization design for steering feel, the parameters of the EPS system and vehicle on steering performance have been investigated. Moreover, the effiects of the parameters on system stability have been analyzed and compared by the method of absolute sensitivity and the results are given in the end.
