“…As the current loop of PMSG control with coupled dq current, it had to add a compensation to improve the dynamic performance, which leads control structure complexity and a lack of robustness. Some references also designed robust, for instance, in [8], a global efficiency optimization of sliding mode control is proposed, in which two chattering-free sliding mode controllers are utilized to control engine speed and PMSG torque; in [12,13], adopts a fuzzy logic control; in [14][15][16] a Dynamic Programming (DP) technology is used to obtain an optimal solution. However, these control strategies such as DP algorithm are not suitable for EREV real-time control; because they are based on masses of driving cycle and a lot of data processing.…”

Abstract:The key to control the range extender generation system is to improve the efficiency and reduce the emissions of the electric vehicle (EV). In this paper, based on the purpose of efficiency optimization, both engine and generator are matched to get a public high efficiency region, and a partial power following control strategy was presented. The engine speed is constant in the defined power range, so the output power regulation of the range extender is only realized by the adjustment of the torque of the generator. Engine speed and generator torque were decoupled. An improved proportional resonant (PR) controller is adopted to achieve fast output power regulation. In order to ensure the response characteristics of the control system and to improve the robustness, the impacts on system's characteristics and stability caused by PR controller and parameters in the inner-current loop were analyzed via frequency response characteristics. A pre-Tustin with deviation compensation is proposed for PR controller's discretization. A stable and robust power following control method is obtained for the range extender control system. Finally, simulation and experiment of the proposed control strategy illustrated its feasibility and correctness.
