EPS system which takes advantage of good current tracking ability, good anti-interference ability, and good operation stability is becoming more and more important in automotive research. The traditional<jats:italic> H<\/jats:italic><jats:sub>\u221e<\/jats:sub> control algorithm can solve the system uncertainty theoretically, but it cannot solve the contradiction between robustness and performance without considering the performance of the system. Therefore, this paper proposes a EPS current tracking method based on the hybrid sensitivity<jats:italic> H<\/jats:italic><jats:sub>\u221e<\/jats:sub> control algorithm, which takes the current tracking performance as one of the control objectives, so that the system can maximize the robustness and performance. Firstly, the dynamic model of EPS is established. Then, the two-degree-of-freedom vehicle model and tire model are introduced. The state space equation of the system is constructed on the basis of the system state space with random disturbance signals, the hybrid sensitivity<jats:italic> H<\/jats:italic><jats:sub>\u221e<\/jats:sub> controller is designed in the sensitivity index design, and the proposed algorithm can use weighting function to minimize the performance of the current tracking error as well as the robustness of the yaw rate error in response to robustness. Simulation analysis and experimental verification of EPS system are also carried out. The results show that the control method of the hybrid sensitivity<jats:italic> H<\/jats:italic><jats:sub>\u221e<\/jats:sub> can better achieve EPS target current tracking, effectively suppress the effect of external interference and noise, improve the system performance and robustness, ensure the driver get good road sense, and improve the system of steering stability.<\/jats:p>","DOI":"10.1155\/2018\/2156980","type":"journal-article","created":{"date-parts":[[2018,6,4]],"date-time":"2018-06-04T19:30:47Z","timestamp":1528140647000},"page":"1-10","source":"Crossref","is-referenced-by-count":5,"title":["EPS
