Experimental evaluation of observer-based throttle valve control using super-twisting algorithm

In this paper, an electronic throttle valve system is considered. The mathematical model describing the motion of the valve plate is subject to uncertainties and external disturbances. The throttle plate angle is intended to track given reference profiles. A control scheme consisting of an observer and a state controller, which both are based upon the super-twisting technique, is proposed. Effectiveness and superiority of the approach are illustrated in numerical simulation using a comparison with a classical control approach. The presented feedback loop is implemented in an engine control unit. Results obtained through comprehensive tests on an industrial combustion engine test bench are given.
