ADAPTIVE CONTROL LAW DESIGN USING DISTURBANCE ACCOMMODATING TECHNIQUES

THE DESIGN OF FEEDBACK CONTROL LAWS FOR SYSTEMS WITH UNKNOWN PARAMETERS AND OTHER SIGNIFICIANT UNCERTAINTIES IS A FUNDAMENTAL PROBLEM IN THE AREA OF AEROSPACE VEHICLE CONTROL. THE APPLICATION OF DISTURBANCE ACCOMMODATING CONTROL (DAC) THEORY TO THIS AREA HAS RESULTED IN A REVOLUTIONARY APPROACH TO THE DESIGN OF ADAPTIVE CONTROL LAWS. THIS APPROACH HAS PROVEN TO BE EXTREMELY EFFECTIVE WHILE, AT THE SAME TIME, AVOIDING MANY OF THE FRAWBACKS ASSOCIATED WITH TRADITIONAL ADAPTIVE CONTROL TECHNIQUES SUCH AS SELF-TUNING REGULATORS AND MODEL REFERENCE-BASED CONTROLLERS.
