[차량운동성능부문] HILS에 의한 전동식 동력 조향 장치 제어 알고리즘 검증

In this paper, the HILS system for performance estimation of MDPS and development of a control algorithm is proposed. In the HILS system, the mechanism for expressing the lateral force of tire in cornering is defined, and verified by ADAMS. A hydraulic actuator basically operated by th sliding mode control and is used for the mechanism, to simulate the effect of real tire lateral force. The flow rate is controlled by the PWM signal transferred from the tire lateral force which is analytically calculated. Through the simulation using the constructed HILS system, the environment that can improve the state of vehicle is realized. The algorithm for a MDPS control is also verified.
