Control for Moment of Motor Inertia on EPS 2006-01-1179

In this research, we investigate the methods for controlling moment of rotational inertia in the electric power steering (EPS) system. We first look at the effects of moment of rotational inertia on conventional EPS systems. Methods for evaluating those effects and countermeasures for controlling the moment of inertia are proposed. After explaining the evaluation method, we describe a design procedure for filters for controlling the moment of rotational inertia by H∞ control method. We also describe the formation of low-order systems of filters obtained, in addition to control block diagrams using filters in the system and their stabilization. Finally, we have equipped a vehicle with this controlled EPS system. The evaluation results have confirmed that the moment of rotational inertia can be satisfactorily controlled.
