Idle speed controller design for SI engine based on ADRC

Abstract

Ahstract-In this paper, an idle speed controller is de signed in the framework of active disturbance rejection control (ADRC) for spark ignition (SI) engine. The SI engine model based on the mean value model is proposed. As the system can be considered as a cascade system, the developed controller in corporates a nonlinear state error feedback law (NLSEF) which handles the speed tracking and an ADRC controller based on the Extended State Observer (ESO) to deal with the unknown dynamics and disturbance of the engine system.The robustness stability of the controller is analyzed. Simulation results are provided to demonstrate the advantage and effectiveness of the controller.

Inferential Active Disturbance Rejection Control of a Heat Integrated Distillation Column Using Dynamic Principal Component Regression Models

“…Non-linear state error feedback (NLSEF) is implemented to calculate the error in the controlled variable by using the nonlinear combination of feedback state error and the outputs from the ESO and TPG. It also combines the disturbance compensation with the error variables to guarantee a good performance of the plant system [21]. The non-linear error feedback law is shown below[22]…”
