Nonlinear control of the electronic throttle under input saturation

Abstract

An electronic throttle is a dc-motor-driven valve that regulates the airflow inside the gasoline engines. Valve plate angle is regulated by controlling the motor voltage, and the motor voltage has the limit range. Nonlinear tracking control of electronic throttle with input saturation is proposed. An auxiliary system is designed to analyze the effect of input saturation, and state of auxiliary design system is utilized to develop the tracking control. Under the proposed tracking control strategy, stability of the closed-loop system is guaranteed via Lyapunov analysis
