On practical control of electronic throttle body

Abstract

An electronic throttle body is a nonlinear device that includes effects on dead time, transmission friction, throttle plate friction and return spring limp-home. The effects are problem to precisely control of electronic throttle regulation. In recent year, various control designs have been proposed. This paper presents a simple yet effective nonlinear controller to enhance the regulator. The regulator is embedded using a discrete fuzzy PI algorithm, provided easy tuning, robustness and rapid development with simple architecture. The effects are also in consideration. The experiment results are carried out and show satisfactory performance using standard criteria such as an integral of absolute error (ITAE), an integral of square error (ISE) and a mean absolute error (MAE).

Designing of Automotive Engine Electronic Throttle Controller for EF7 Engine

“…Model of DC Motor consists of a resistor, inductor and non electromotive voltage [2,3]. In figure 1 these parts has been demonstrated.…”

“…For accurate controlling of this type of throttle, physical model must be recognized. In this research at first a physical model has been yield by mechanical equations then for recognizing of unknown parameters, estimation method was used [2][3][4].…”

Stability Analysis and Chaos Control of Electronic Throttle Dynamical System

“…However, electronic throttle systems face two major problems: the nonlinear spring and the friction force in the valve [12]. Because electronic throttle valve systems feature many nonsmooth nonlinearities, the system is very hard to control [13][14][15]. Several studies have investigated nonlinear control for electronic throttle systems [16][17][18][19][20], which are typically depicted by a nonlinear dynamical system [13,17].…”
