Analyzing Control/Structure Interactions

CO-ST-IN computer program developed to facilitate study of control/structure interactions; dynamic coupling between control systems and flexible structures. Works in conjunction with other programs to enhance analysis of vibrations. Designed to complement and enhance rather than replace software tools for analysis of control systems and dynamics of structures. FORTRAN 77 program.

Control of a Flexible Space Antenna: A Finite Dimensional Perspective Based on Distributed Parameter Theory

The methods presented are based on results from infinite dimensional control theory, but they can be described and used in a finite dimensional context. This blend leads to an approach which employs powerful ideas on convergence, and is also quite practical for systems of realistic complexity. Appropriate reduced order models are generated simultaneously with the development of the compensator. The required models change as a function of changes in the performance demanded, sensor and actuator location, inherent damping, disturbances, etc. Thus they are driven by the control and estimation problems at hand. The compensators which emerge are very close to the ideal compensators which would be obtained with a very large order model. However, some simplification is frequently possible. The method of balanced realizations was found to be effective for this purpose.
