Abstract
In order to achieve a good shifting quality of pure electric vehicle dual-clutch
transmission, this paper adopts linear active disturbance rejection controller
(LADRC) to control the shifting strategy. For the uncertainty of transmission
dynamics model parameters and the existence of unknown disturbance effects, the
linear expansion state observer (LESO) can be used to estimate and compensate
the disturbance. The shift control process is converted into tracking the motor
speed and clutch speed trajectory, and the linear feedback control law is used
to control the motor torque and the solenoid valve current. The simulation and
test results show that the control algorithm is effective and good shifting
quality is guaranteed.
