Wireless Position Control of an Electric Power Steering System for Energy Optimization

Abstract

This paper proposed an energy optimization strategy with an optimal control method approach based on wireless position control of electric power steering (EPS). The optimal control method consists of a discrete linear quadratic regulator (DLQR) as case-1 and a predictive control model (MPC) as case-2. Both are applied to see the potential of the optimal energy based on the comparison of control performance, resulting in a control design that eliminates unwanted vibrations and ensures system stability, and energy efficiency. In addition, both of these control designs can be implemented in a wireless system for position control of EPS using a mobile phone.
