On practical control of electronic throttle body

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). © 2012 IEEE.
