Study on the Power Control Algorithm Using the Gradient Method

This paper presents a power control algorithm that will make it possible to apply a torque assist system (TAS) without reconfiguring the structure of an internal combustion engine (ICE) vehicle. Several optimal control ideas for hybrid electric vehicles (HEVs) have been proposed in the literature. In this study, the algorithm implements a gradient optimization technique. This suggested algorithm considers the states of the motor starter generator (MSG) and energy storage, as well as the maximum efficiency of the engine. To optimize the engine efficiency under various driving conditions, the algorithm considers the driver’s demand outputs. It will be utilized for optimization based on TAS. 1156 Gyoung-eun Kim, Jae-woo Yoon and Byeong-woo Kim The use of the proposed algorithm will contribute to the research in this field by controlling the performance of the engine and MSG at efficient operating points to match the driver’s demand outputs.
