Resumen
ARE THE ONLY NATIVE VASCULAR SPECIES OF PLANTS IN THE ANTARCTICREGION AND ARE A SOURCE OF INTEREST IN THE CLIMATE CHANGE STUDIES.THESE PLANTS HAVE BEEN STUDIED FOR DECADES AND RECOGNIZEDAS BIOINDICATORS OF THE CLIMATE CHANGE. THE ARTICLE PRESENTSPRELIMINARY STUDIES AND RESULTS OF A THERMAL ACTUATOR, WHICH ISGOING TO BE APPLIED IN A CLIMATE CHANGE STUDIES. THE ELABORATED,FAR INFRARED ACTUATOR TOGETHER WITH A CONTROL SYSTEM MAINTAINSTHE TEMPERATURE OF THE ANTARCTIC PLANT CERTAIN DELTA ABOVE THEAMBIENT TEMPERATURE. SINCE THE HEAT TRANSFER IS BASED ON INFRAREDRADIATION A THERMAL MODEL IS INTRODUCED, WHERE THE PARAMETERSOF THE MODEL ARE DETERMINED EMPIRICALLY APPROXIMATING IT USING A1-ST ORDER DYNAMICAL SYSTEM. ONCE DETERMINED, THE SYTEM MODELPAREMETERS HELP TO DESIGN THE CONTROL STRATEGIES: CONTROL ON-OFF(1) AND CONTROL PID (PROPORTIONAL?INTEGRAL?DERIVATIVE) (2). ASA RESULT WE OBTAIN THAT THE CONTROL PID MAINTAINS THE OBJECTSTEMPERATURE WITH MAJOR STABILITY THAN ON-OFF, WHAT MAKES ITPREFERABLE IN THE ?NAL APPLICATION. THE FUTURE WORKS INVOLVEMODELING AMBIENTAL PERTURBATION, WHICH AFFECTS THE SYSTEM ANDDETERMINATION THERMAL PARAMETERS OF THE ANTARCTIC PLANTS.
