Abstract
Development of a mathematical model of air to fuel ratio and control for SI engines has been proposed in various themes to satisfy technical specification. This paper reveals a simple yet effective nonlinear control to enhance the regulator. The mean value engine model (MVEM) is employed and enhanced to validate the effectiveness of the proposed scheme. The regulator is designed using a discrete fuzzy PI algorithm, provided easy tuning, robustness, and rapid development with simple architecture. Effects on dead time, exhausted delay, and chaotic disturbance are also included. The simulation results show satisfactory performance using standard criteria such as an integral of absolute error (ITAE), an integral of square error (ISE) and an integral of absolute control output (IACO) and a mean absolute error (MAE). © 2012 IEEE.
