This paper presents a new algorithm to determine optimal operation mode of HEV to estimate the distribution of electricmechanical power. The simulation results and experience indicate the validity of the proposed algorithm. The obtained results can be applied in practice to improve qualities of HEVs in Vietnam. | Journal of Automation and Control Engineering Vol. 4, No. 2, April 2016 A New Method to Design Optimal Power Compensator in Hybrid Electric Vehicles Hoang Mai Nguyen1, Tien Dung Le1, Le Hoa Nguyen1, and Quang Vinh Doan2 1 University of Science and Technology-The University of Danang, Danang, Vietnam 2 The University of Danang, Danang, Vietnam Emails: {nhmai, ltdung, nglehoa}@, dqvinh@ Abstract—The most important task for hybrid electric vehicles (HEV) is to optimal control of the distribution of the electric and mechanical powers in the system. Despite many studies have been focused on this issue, there are still many methods to fully exploit the capacity as well as re-charge power in other operating modes of HEV. This paper presents a new algorithm to determine optimal operation mode of HEV to estimate the distribution of electricmechanical power. The simulation results and experience indicate the validity of the proposed algorithm. The obtained results can be applied in practice to improve qualities of HEVs in Vietnam. n T Tk where Tk including: the body force T1, weight load T2, torques of four-wheels T3 . T6, friction force T7, environmental noise such as wind power, pressure difference T8, and elastic force T9 caused by the tires. Here, fluctuating component of the fuel in the tank is ignored. At the time of vehicle parameters are determined through three motion coordinates x, y, z, and angles respectively. For models depicted in Fig. 2 and [1], we can obtain the dynamic equations as follows: Index Terms—hybrid car, HEV, optimum control, robust control, split power, combustion, engine, fuel consumption 6 k 1 k 1 I The car is a motion hanging system that its weight load and fuel can be changed in practice. Therefore, the inertial of the car also can be changed. Because, the road is not smooth, therefore, the car can be controlled in three directions of motion, corresponding to three variables x, y, z in the .
