Variable structure control of electronic throttle valve

Abstract

The use of an electronic controlled throttle valve can increase the efficiency and performance of an engine since the control of the throttle valve, which is determined according to the desired amount of air flow calculated from the desired speed and engine torque, is independent from the position of the accelerator. In this paper, a variable structure (VS) controller is designed for the electronic throttle valve. The model of the electronic throttle valve is discussed at first. Then the VS controller is proposed by using the backstepping approach. Finally, simulation and experimental results are given.
