Description
Summary:Automated clutch is an important module in automated manual transmission. Clutch engagement control plays a crucial role, since different and conflicting goals have to be satisfied: preservation of driver comfort, fast engagement and small friction losses. In this paper, a proposed optimal control strategy to improve the clutch starting-up quality of automated manual transmission vehicles during starting-up phase, based on LQR combined with Pontryagin's maximum principle is developed. Based on the friction clutch dynamics, a plant model is designed with engine speed and clutch slip speed as state variables and the rate of change clutch clamping force as a control variable. Matlab/Simulink platform has been used to simulate the controller performance for different operating conditions. Simulation results revealed that the control strategy improves the starting-up quality in achieving fast engagement, reducing clutch frictional power loss and minimizing the jerk.
