H∞ launch control of a dry dual clutch transmission based on uncertain TS models

In the literature, there are two types of vehicle transmission, the manual transmission and the automatic one. The dual clutch transmission combines the advantages of an automatic transmission with better performances especially in terms of fuel consumption. In this system, the management of the clutch is a key point when considering driving comfort during the launch and gearshift. This paper proposes a control law for clutch engagement during the launch phase based on a Takagi-Sugeno (TS) approach. The goal is to ensure a smooth clutch engagement while limiting slipping clutch, and avoiding engine to stall. To achieve this goal, a strategy using the clutch slipping speed and engine speed is proposed. In addition to this, some parametric variations of the model and disturbances are also considered. Several simulations results are provided to show the efficiency of developed control law.
