Abstract :
This article is concerned about the analysis, design, and simulation of an electric power steering (EPS). The article begins by introducing the EPS system concept and comparing the technical and commercial benefits with existing technologies. Being more versatile than conventional hydraulic power steering, EPS systems excel in engine efficiency, space saving, and environmental friendly. The remainder of the article is focused on the fuzzy logical control scheme in details elaborating on the fuzzifying, editing FIS and membership function and defuzzifying. The simulation model of EPS is set up based on its characteristic equations and on the principle of fuzzy logic control. At last, a series of tests are performed and some characteristic pictures are demonstrated. The feasibility, high reliability of the system and the validity of the control method are proved by the fruitful results which serve an instrumental meaning for a further research.
