Abstract

This paper presents a novel method for sigma point (SP) selection in the context of the unscented transform (UT). Such a method yields an asymmetric SP set, which can be especially useful in failure prognosis applications. The proposed method can be employed to overcome performance limitations associated with the application of conventional UT for the estimation of remaining useful life (RUL) of equipment, while maintaining the benefits yielded by the use of the UT in this task. Sample applications based on simulated and real data of aircraft systems degradation are presented to illustrate and validate the concept. Results indicate that the proposed method yields improved RUL estimation results at lower computational cost when compared to the original UT. (AU)
