Robust model-based controller synthesis for the SCOLE configuration

Abstract

The design of a robust compensator is considered for the SCOLE (spacecraft control laboratory experiment) configuration using a frequency-response shaping technique based on the LQG/LTR (linear quadratic Gaussian/loop transfer recovery) algorithm. Results indicate that a tenth-order compensator can be used to meet stability-performance-robustness conditions for a 26th-order SCOLE model without destabilizing spillover effects. Since the SCOLE configuration is representative of many proposed spaceflight experiments, the results and design techniques used should be potentially applicable to a wide range of large-space-structure control problems.<>
