Abstract

Objectives for the idle speed control problem in an internal combustion, spark ignited engine are basically to achieve smooth engine operation at idle speeds, under significant accessory load disturbances. Previous work has focused on this problem for models developed in the time domain and, more recently, in the crank-angle domain, primarily for linear designs. In this paper, we present simulation results in a comparative analysis for linear and nonlinear control design techniques, for application to a simplified model of the GM V6 3800 IC engine. The control inputs are air and spark, and our focus will be on an engine model for control design that is based on the crank angle as the independent variable
