Second-order sliding mode control of electronic throttle valves

Higher-order sliding mode concepts eliminate undesired chattering arising in classical variable structure systems. In this paper the control of electronic throttle valves based on second-order sliding mode control is outlined from a practical point of view. First two control strategies, namely the twisting algorithm and the super-twisting algorithm, are tuned by numerical simulations. Then the realtime implementation of the control laws using Matlab is demonstrated. Finally experimental results are presented.
