Set Up

Aiming at the characteristics of the all-electric logistics machines, the paper established the multi-disciplinary mathematical models of the electric power steering system (EPS) and set up a semi-physical simulation platform based on dSPACE for the multi-domain system of EPS. The robust control method was applied to improve the EPS system for the stable actual output of the EPS multi-domain system in the uncertainty. By the real-time semi-physical simulation, the control features of the improved EPS multi-domain system were analyzed so as to increase the robustness and adaptability of the EPS system.

Electric Power Steering System

Electric power steering is an advanced steering system that uses an electric motor to improve steering comfort of the car. As a result, the failures in the electric motor can lead to additional fault modes and cause damage of the electric power steering system performance. Hence, to ensure the stability of this latter, the present paper proposes a new method to reconfigure the fault control. A novelty approach of fast fault estimation based on adaptive observer is also proposed. Moreover, to guarantee optimal and fast control, a fault-tolerant control based on inverse bond graph modeling is designed to construct the behavior of the nominal system. The simulation and the experimental results on a real electric power steering system reveal the importance of the control strategy and show that the proposed approach works as intended.
