Adaptive structures for large precision antennas

Abstract

Optimal controller design approach for high precision pointing maneuver of flexible spacecraft by using adaptive structures is investigated in this paper. A parameter optimization technique is used to find out controller parameters minimizing a desired objective function which represents pointing performance of a flexible space structure. Multi-input and multi-output configuration used in this study also provides insight on the effectiveness of actuator location for improved performance. Copyright (C) 1996 Elsevier Science Ltd
