GEAR SHIFT CONTROL FOR AUTOMATED MANUAL TRANSMISSIONS

Abstract

The automated manual transmission and the dual-clutch one use conventional
synchronizers to shift gears. However, unlike a manual transmission on these
transmissions gear shifting is done through a controller. The actuator can be a
hydraulic cylinder or an electric motor, of which the electric motor type actuator is
commonly used. Base on the synchronizer dynamics model, the authors design a PD
controller to perform gear shifting control. The simulation results with the designed
controller are compared with the open-loop control.
