H∞ Robust Control for Twin Clutches of DCT during Vehicle's Starting and Shifting Processes
摘要
Abstract
Based on the structure and working principles of DCT, some dynamic models during the vehicle's starting and shifting processes were built. Considering the uncertain factors such as engine torque fluctuation and jitter of gas pedal during the vehicle's starting and shifting processes, a H∞ robust controller was designed based on the Riccati inequality and the LMI, the jerk and the slipping friction work which standed for the two performance indexes of clutch engaging were analyzed, the optimal pressure of twin clutches was obtained using the above H∞ robust control method. And relative simulation analyses were made comparing with linear quadratic optimal control algorithm. Simulation results indicate that the provided H∞ robust control strategy can resolve the problem of the clutch pressure control effectively during the vehicle's starting and shifting process and greatly improve the robustness of clutch control.关键词
