H∞ gearshift control of a dual clutch based on uncertain TS models

The dual clutch transmission was introduced in vehicles to improve driving comfort compared with manual transmissions, and performances, fuel efficiency compared with automatic transmissions. The dual clutch transmission allows to shift gears quickly, comfortably and without interruption in traction. In the dual clutch transmission, the management of the dual clutch in the gearshift phase is a key point especially when considering driving comfort. In this paper, we propose a dual clutch control law for gearshift based on a Takagi-Sugeno model. The goal is to ensure a smooth gearshift while limiting shift time. The approach used is the tracking of the dual clutch sliding speed and engine speed reference. In addition, parametric variations of the model and disturbances are also considered.
