Article: Four-mass-PWA model-based robust H∞ coordinated control strategy for MTP of DM-PHEV Journal: International Journal of Vehicle Design (IJVD) 2023 Vol.92 No.2/3/4 pp.149 - 172 Abstract: The multiple actuators of plug-in hybrid electric vehicles (PHEVs) participating in mode transition process (MTP), including engine start, clutch slipping and engagement. However, the engine start and clutch slip process involved in the MTP may lead to complex dynamics. In this paper, a 13 degrees of freedom dynamic model of dual motor plug-in hybrid electric vehicle (DM-PHEV) is built and according to the results of sensitivity analysis, the model can be simplified as a four-mass model which is more friendly to the design of controller. Furthermore, the non-linearities caused by the engagement of clutch are handled with a piecewise affine (PWA) modeling method, and the vibration attenuation is realised by designing a PWA model-based robust H∞ coordinated control strategy. Simulation and hardware-in-the-loop (HiL) test demonstrate that compared with the controller based on conventional two-mass model, the vehicle jerk controlled by proposed controller based on four-mass model can reduce the vehicle by 89.38%.
