Robust nonlinear dynamic inversion control for electric throttle

Abstract

This paper presents a nonlinear control strategy using robust nonlinear dynamic inversion (RNDI) for an electric throttle which is a dc-motor driven valve for automotive engines. Controlling of the electric throttle is a great challenge due to strong nonlinearities, such as "limp-home" nonlinearity, friction and backlash. In this paper, a novel robust nonlinear dynamic inversion technique is proposed in order to achieve a fast and accurate reference tracking performance even in the presence of highly nonlinear characteristics. The effectiveness of the proposed method is analyzed through computer simulations.
