Wing anti-icing system control modeling and sensitivity analysis: A system identification based approach.

摘要

Accretion of ice along the wing leading edge can pose a serious threat to aircraft safety. Thermal anti-icing systems are commonly used to prevent ice formation along the wings. University of Toronto Institute for Aerospace Studies has initiated a research project in developing a generic wing anti-icing control and simulations system. As part of this research initiative this thesis presents the development of a dynamic model of an anti-icing system using a system identification based approach, and an investigation of the sensitivity of the system to changes in the control parameters and location of the temperature sensor. The results of this sensitivity analysis were used in tuning the controller and finding an optimum location for the feedback temperature sensor. This study indicates that the system identification approach is an effective tool for modeling dynamic systems based on test data for the purposes of controller sensitivity analysis and tuning.
