Morphing structures are multifunctional structures in which the geometry, shape and parameters vary with the functionality and time. Such morphing structures are used in mechanical systems such as cranes and adaptive or morphing aircraft. Span morphing aircraft is an aircraft in which the geometry can be changed during the operation. Due to its complexity in mathematical modelling, system identification (SI) methods are investigated to model a telescopic type morphing beam in the current study. The system is formulated as a beam subjected to moving loads which results in time varying parameters. The dynamic response data, generated with theoretical models shows that the system switches from time varying to time invariant system, moving window methods are used to identify the system. Stages of data preparation, model and model order selection, model evaluation and further developments are discussed in the paper.
