FINITE STATE ATTITUDE CONTROL.
Abstract
The design of control systems which have an overall reliability measured in years, rather than days or hours has always been objective, but has become increasingly more important with the advent of the possibility of sustained space flight. This report presents a new approach to the synthesis of attitude control systems. The resultant controllers, by virtue of their simplicity and the attendant possibility of multiple redundancy, seem to hold promise in achieving high reliability. The approach consists of relegating the system dynamics and transfer functions to a secondary role, emphasizing the development of behavior rules instead, and then applying conventional digital asynchronous design techniques to synthesize the controller. The application of this approach to the design of controllers is illustrated by several examples. Among them are a time-optimal approximation, a min-max rate controller and a controller operating only upon dead-zone information. (Author)
