Flexible Space Structures

This paper addresses design of nonlinear control systems for rapid, large angle multiaxis, slewing and LOS pointing of realistic flexible space structures. The application of methods based on adaptive feedback linearization for nonlinear control design for flexible space structures is presented. A comprehensive approach to modeling the nonlinear dynamics and attitude control of multibody systems with structural flexure is considered. Adaptive feedback linearizing control laws are described based on Lagrangian dynamical system model for the spacecraft. Simulation results for attitude slewing and LOS stabilization for the NASA/IEEE Spacecraft COntrols Laboratory Experiment (SCOLE) design challenge are presented.

Nonlinear Equations Of Motion

A multibody dynamics formulation for studying the response of large space structures with interconnected flexible bodies is presented. The use of system modes to model the structural flexibility results in a compact form of the nonlinear equations of motion. Next, the nonlinear control based feedback linearization technique is applied to effectively control the attitude motion of a flexible space platform. Using the original nonlinear dynamics of the multibody system, the controller determines the effort to effectively linearize the system and introduces a linear compensator to achieve the desired output in the presence of structural flexibility of the spacecraft.

Historical Role

AbstractLast five decades witnessed remarkable developments in linear control systems and thus problems in this subject has been largely resolved. The scope of the present paper is beyond linear solutions. Modern technology demands sophisticated control laws to meet stringent design specifications thus highlighting the increasingly conspicuous position of nonlinear control systems, which is the topic of this paper. Historical role of analytical concepts in analysis and design of nonlinear control systems is briefly outlined. Recent advancements in these systems from applications perspective are examined with critical comments on associated challenges. It is anticipated that wider dissemination of this comprehensive review will stimulate more collaborations among the research community and contribute to further developments.
