Active Control of Linear Periodic Systems.

Abstract

The linearized equations describing the attitude motion of two generic satellite cases are developed. In both cases, the symmetric satellite in an elliptical orbit and an unsymmetric satellite in a circular orbit, the linearized equations are periodic. Uisng Floquet theory, the stability of the attitude motion for several satellite designs is checked. For satellites with unacceptable attitude stability, an active control scheme utilizing modal control design techniques is developed. With this control scheme, various satellite test cases are stabilized and the results are verified via a digital simulation of the satellite attitude motion.
