Abstract
Abstract – The electronic throttling angle control system is the newly common requirement trend in automotive technology. It is used to regulate the amount of air flow into the engine. Due to the existence of multiple non-smooth nonlinearities, the controller design to the electronic throttle valve becomes a difficult task. These nonlinearities including stick–slip friction, backlash, and a discontinuous nonlinear spring involved in the system. The designed controller in the present work consists of the estimated perturbation term with a negative sign (used to cancel the perturbation term) and a stabilizing term used to stabilize the nominal system model. The perturbation term consists of the external unknown input and the uncertainty in throttle valve model including the nonlinear terms. The utilized estimator uses the sliding mode control theory and based on the equivalent control methodology. The simulation results show the effectiveness of the proposed controller in estimating the perturbation term. And then in forcing the angle of the throttle valve to follow the desired opening angle in presence of nonlinearities and disturbances in throttle system model and the variation in its parameters.
