Research on Control Strategy and Simulation of Electric Power Steering System for Electric Power Bus

A kind of recirculating ball-type power steering system for electric power bus was designed. The control strategy of EPS is divided into two layers that are top layer strategy and bottom layer strategy. The assist mode of top layer strategy is researched. The simulation model based MATLAB/Simulation was build and verified by the simulation experiments. The results validate the effectiveness of the proposed strategy, which creates the research basis for further research and development of EPS.
