Abstract :
In this paper, a mathematical model of electric power steering (EPS) system is set up through the dynamic analysis of EPS system. H infinity controller is designed using robust control theory to aim at the disturbance and sensor noise which exist in the system. A simulation using MATALAB/SIMULINK is performed. The results show that the electric power steering system with H infinity controller has a good performance.
