Attitude Control of an Axially Symmetric Rigid Body under Failure.
Abstract
The response of an axially symmetric, extended rigid body to a failure in one control effector is analyzed. The failure produces an unknown constant disturbance force and moment which induces cross-axis coupling that seriously degrades the author response. The cross coupling makes it necessary to consider the three attitude axes simultaneously. Nonlinear equations of motion are required because large amplitude attitude changes are of interest. The principal problem considered is to synthesize an attitude control system which can respond to the failure by modifying its structure and parameters on-line to improve its attitude control.
