Design of an ADRC-based electronic throttle controller

Electronic throttle control is increasingly being considered as a viable alternative to conventional air management systems in modern spark-ignition engines. In this paper, an active disturbance rejection controller (ADRC) is proposed for the electronic throttle control. The ADRC controller consists of a linear extended state observer (ESO) to estimate the total disturbance and a linear state error feedback controller. The simulation results show that the ADRC controller can adapt well to the nonlinearity of electronic throttle system and has strong robustness to model uncertainties, and the experiment results are provided to demonstrate the effectiveness of the proposed controller.
