Stability, Observability, Controlability and Frequency Response of a VO2 Optoelectronic Commuter, Assuming it as an Input-Output Device in the TF, SS and ZPK Representations

Abstract

 Optoelectronic switches based on VO2 thin films are analyzed as input-output devices (I/O) of multiple responses to stimuli of electric tension, temperature and energy of the incident electromagnetic radiation. The representations used are based on their transfer function (TF), in the space state (SS) and in the representation of poles, zeros and gain (ZPK). Starting from there, the stability, observability, controllability and frequency response of these systems are investigated, which contributes to a better understanding of the operation of these devices and their potential applications.
