APPLICATION OF THE RATE DIAGRAM TECHNIQUE TO THE ANALYSIS AND DESIGN OF SPACE VEHICLE ON-OFF ATTITUDE CONTROL SYSTEMS

Abstract

Preliminary single axis analysis and design of a space vehicle control system, consisting of a torque producing device and a dead-band within which there are no externally or internally applied torques, can be accomplished quite effectively by a simple graphical technique termed the Rate Diagram method. Two characteristics of typical space vehicle attitude control problems which make this method effective are the undamped rigid body motion of the vehicle and the associated low angular rates. The characteristics satisfy the required assumptions that the vehicle angular acceleration be proportional to the applied torque, and that system transients effectively decay prior to control torque application. The system, exclusive of the vehicle dynamics, can be of any order, thu allowing sensor dynamics, shaping networks, and control torque characteristics to be included.
