Summary:Based on a certain manual transmission of a heavy duty truck, a dual clutch transmission (DCT) structure was proposed and the simulation model was built by means of Matlab/Simulink. The control strategy, that the engine speed was controlled to follow the target speed, was put forward. Exact mathematical model of DCT is difficult to gain, thus fuzzy controller was adopted to control the engine throttle and oil pressure. After analysis of the shortcomings of traditional fuzzy control, improved fuzzy control method was proposed to improve the launch performance. The integral term is added as an offset to the system to accelerate the movement of the process towards set point and eliminate the residual steady-state error. Simulation results show that improved fuzzy control method can yield better launch quality. The simulation model can provide a useful analytical tool for further development of such gearboxes.
