A Comparison of Extended Kalman Filter Approaches Using Non-linear Temperature and Ultrasound Time-of-flight Measurement Models for Heating Source Localization of a Transient Heat Transfer Problem

ABSTRACT State estimation procedures using the extended Kalman filter are investigated for a transient heat transfer problem in which a heat source is applied on one side of a thin plate and ultrasonic time of flight or temperature is measured on the other side of the plate. A forward conduction solution is developed using finite element methods and… (More)
