International Telemetering Conference Proceedings / October 18-21, 2004 / Town & Country Resort, San Diego, California / CCT is conducting research to provide a cross platform software capability that enables a common semantic for control and monitor of highly distributed systems-of-systems C^2 architectures by auto-generating semantic processing services from standardized metadata specifications. This new capability is significant because it will reduce development, operations, and support costs for legacy and future systems that are part of ground and space based distributed command and control systems. It will also establish a space systems information exchange model that can support future highly interoperable and mobile software systems.

International Telemetering Conference Proceedings / October 17-20, 1988 / Riviera Hotel, Las Vegas, Nevada / The Multi-Vehicle Metric & Telemetry System (MMTS) is a complete range system which performs real-time tracking, command destruct, and telemetry processing functions for support of range safety and the test and evaluation of airborne vehicles. As currently configured, the MMTS consists of five hardware and software subsystems with the capability to receive, process, and display tracking data from up to ten range sensors and telemetry data from two instrumented vehicles. During a range operation, the MMTS is employed to collect, process, and display tracking and telemetry data. The instrumentation sites designated for operational support acquire tracking and telemetered data and transmit these data to the MMTS. The raw data is then identified, formatted, time tagged, recorded, processed, and routed for display to mission control and telemetry display areas. Additionally, processed tracking data is transmitted back to instrumentation sites as an aid to acquire or maintain vehicle track. The mission control area consists of a control and status console, high resolution color graphics stations, and large screen displays. As the mission controller observes mission progress on the graphics stations operational decisions can be made and invoked by activation of the appropriate console controls. Visual alarms provided my MMTS will alert mission control personnel of hazardous conditions posed by any tracked vehicle. Manual action can then be taken to activate transmission of the MMTS vehicle destruct signal. The telemetry display area consists of ten fully-functional, PC compatible computers which are switchable to either of two telemetry front end processors. Each PC can be independently set up by telemetry analysts to display data of interest. A total of thirty data pages per PC can be defined and any defined data page can be activated during a mission. A unique feature of the MMTS is that telemetry data can be combined with tracking data for use by the range safety functions.

Η παρούσα διδακτορική διατριβή στοχεύει στην μελέτη και ανάλυση μεταβλητών συστημάτων με απώτερο σκοπό την ανάπτυξη αλγορίθμων στο χώρο της αναγνώρισης συστημάτων, πρόβλεψης εξόδου αυτών, και δημιουργίας προσαρμοστικών ελεγκτών που θα επιδεικνύουν σθεναρότητα απέναντι στις μεταβολές των υπό μελέτη συστημάτων. Η μεταβολή στα συστήματα αυτά προκύπτει κυρίως από την εισαγωγή τυχαίων χρονικών καθυστερήσεων στην είσοδο και στην έξοδο αυτών. Οι καθυστερήσεις αυτές, είναι δυνατόν να είναι σταθερές ή μεταβαλλόμενες, γνωστές ή άγνωστες, ντετερμινιστικές ή στοχαστικές. Σαν τελικό αποτέλεσμα οι εισαγόμενες χρονοκαθυστερήσεις είναι δυνατόν να αλλάξουν την συμπεριφορά του συστήματος οδηγώντας αυτό στην αστάθεια. Στην παρούσα διδακτορική διατριβή προτείνονται μέθοδοι μοντελοποίησης αυτών των χρονοκαθυστερήσεων σε συνδυασμό με τους αλγορίθμους αναγνώρισης και πρόβλεψης εξόδου συστημάτων υποκείμενων σε αυτές τις χρονικές καθυστερήσεις. Επιπροσθέτως παρατίθενται πρότυπες και κατάλληλα διαμορφωμένες δομές προσαρμοστικού ελέγχου και μελέτης της ευστάθειας αυτών των συστημάτων. / The aim of this dissertation is the study and analysis of varying systems, as also the development of algorithms in the field of: a) system identification, b) system prediction, and c) adaptive control that will be able to be robust to the variations of the systems under study. These variations in these systems are induced mainly from the insertion of time delays in the input and output of those systems. These delays can be constant, or varying, known or unknown, deterministic or stochastic. As a final result these time delays can alter the behavior and the performance of the system while driving it to instability. In this dissertation new algorithms are proposed for the modeling of these time delays in conjunction with the algorithms for the identification and output prediction of systems with time delays. Additionally new algorithms of adaptive control and stability analysis of the controlled systems are proposed.
