Abstract

In this paper, the problem of optimal decoupling of engine idle speed and emission subsystems is studied for facilitation of modularization of control tasks, enhancement of robustness, reduction of control complexity and calibration time, and improvement of engine system performance. A new design method is introduced which employs feedforward compensation to achieve optimal decoupling of engine subsystems over large frequency ranges. The design method is applied to the decoupling of engine idle speed and emission subsystems which demonstrate significant reduction of their interconnections
