Abstract

To improve the shift quality of vehicle with clutch-to-clutch gear shifts, a nonlinear controller is designed for the clutch slip control during the inertia phase. Backstepping technique is used to deduce the control algorithm. Model uncertainties including steady state errors and unmodelled dynamics are also considered as disturbance inputs and the controller is designed such that the error dynamics is input-to-state stable (ISS). Finally, the designed controller is discretized and tested on a complete powertrain simulation model.
