Abstract:
Active front steering(AFS) can improve dynamic steering characteristic of the vehicle, but the model nonlinear and parameter decoupling control process are complex in traditional control methods. Therefore, a control method of AFS based on active disturbance rejection technique is proposed. In control method of active disturbance rejection, extended state observer (ESO) among of active disturbance rejection controller(ADRC) dynamically estimates internal and external disturbance of system according to the input and output of system, which can easily realize the model nonlinear and parameter decoupling control. The AFS controller consists of the proportional
