Abstract :
An electronic throttle is a dc servo drive which positions the throttle plate, thus providing drive-by-wire control of engine torque. In this paper, an approximate model-based robust nonlinear control (AMRNC) strategy is proposed for electronic throttle valve. The AMRNC includes two main parts: approximate model controller and uncertainty compensation. The approximate model controller, utilized as a feedforward controller, is developed from a linearization of the input-output model of the plant using Taylor expansion technique, and it is implemented using fuzzy system modeling. Moreover, a robustness filter in the feedback structure is employed as uncertainty compensation. The robust stability is established by Lyapunov stability theorem. A simulation and an experiment are provided to verify the effectiveness of the AMRNC strategy.
