Vehicle longitudinal acceleration active disturbance rejection control: The active disturbance rejection control (ADRC) method is used to study the vehicle longitudinal acceleration control. Firstly, the engine dynamic model and the vehicle longitudinal dynamic model with the throttle opening command as the control variable are given, and ADRC is briefly introduced; then the model is transformed into an affine system suitable for active disturbance rejection control, and the vehicle longitudinal acceleration ADRC controller is designed; finally, simulation is carried out under the environment of vehicle and engine parameter perturbation and road disturbance. The results show that the ADRC controller can enable the vehicle to obtain fast, smooth and high-precision acceleration control effect. Keywords: vehicle; longitudinal acceleration; engine dynamic model; throttle control; active disturbance rejection control
