Control of electronic throttle valve using model predictive control

Electronic throttle valve is used in automobile industries very extensively. Its main function is during combustion process to adjust air-fuel ratio by varying the valve plate angle. Generally this valve plate is attached to the accelerator. It implies that control of valve plate is done by driver. Therefore, climatic, road and fuel conditions do not come into consideration. However, this throttle valve consists of much non-smooth nonlinearities like stick-slip friction, backlash and a discontinuous non-linear spring. These nonlinearities make the control of throttle valve very difficult. In this paper model predictive control has been attempted to control the angular position of electronic throttle valve.
