Multiple fuel injection events are now possible with high pressure common rail systems. The air path system can be controlled using combinations of actuators and advanced turbocharger systems. This increased flexibility dramatically increases the complexity of the control strategy and calibration efforts needed for new engine platforms. This study presents a new control structure for diesel engines using scheduling variables that are related to the cylinder conditions. This can reduce the number of calibrations needed compared to conventional techniques. </p><p>A list of candidate parameters to be used as the scheduling variables is developed. Accurately quantifying the scheduling variables during engine operation is a primary requirement for the control structure to function effectively. Equations for each of the parameters are developed based on production sensors and models. The quality in predicting the parameters is derived based on the uncertainties in the models and measurements resulting in analytical uncertainty equations. These equations can be applied to any engine platform providing support for control input selection paired with the most appropriate sensing system. The uncertainty equations are applied to a 2.8 L diesel engine to show the application and benefit to quantifying the uncertainty in the control inputs.</p> 2010-10-26 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1282067559 http://rave.ohiolink.edu/etdc/view?acc_num=osu1282067559 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
