The purpose of this project was to develop a technique that will reduce the need for high-fidelity models for the control synthesis process, provide a robust control implementation, and relieve computational burdens by utilizing artificial-intelligence techniques, notably expert systems, to implement control systems for large SDI space systems. Extending an earlier proof-of-concept investigation, this research proceeds beyond simple control laws, low bandwidths, and exact pattern encoding/matching approaches to include modern control laws, higher bandwidths, and partial match-inferencing procedures. Three control implementations, Direct-Velocity Feedback, Independent Modal Space Control, and an Expert-System Controller were developed and various simulations performed to verify and compare performance. The primary finding is that an ESC has performance comparable to the numeric approaches and has a superior performance when there are changes in the system being controlled. That is, an ESC indeed demonstrates a robust control implementation.
