520 | |a"This study presents a graphical method for the design and analysis of a flexible spacecraft controller. It can handle as many modes as desired, in constrained or unconstrained form;modal separability is not assumed and the method is exact when the spacecraft axes are uncoupled. The definition of a 'system function', independent of the controller parameters, simplifies the determination of the system stability boundaries. It also allows the investigation of the modal separability assumption, resulting in a criterion for its validity. Stabilization through structural damping and flexible modes filtering is illustrated using graphs of the system function. Closed-form approximations are derived in order to complement the exact, numerical method. Extensions to systems with loop delay andnonlinear elements are also included along with applications to the LSAT-1 Roll axis"--Abstract. |
