Control of an electronic throttle valve based on concepts of sliding-mode control

This paper deals with the design of controllers for electronic throttle valves, which are used in combustion engines for adjusting the air-fuel-ratio. First a simplified model of the throttle valve is presented. Nonlinear phenomena like stick-slip-friction and gear-backlash are neglected. In order to cope with these uncertainties as well with the modelpsilas discontinuous right hand side, concepts of sliding-mode control are applied. A standard integrating sliding-mode controller is opposed to a higher order concept, namely the super-twisting algorithm. Finally experimental results are presented and discussed.
