Abstract
This article explores the design of a new position loop controller for the 34-m High Efficiency Deep Space antennas using linear quadratic (LQ) optimal control techniques. The LQ optimal control theory is reviewed, and model development and verification are discussed. Families of optimal gain vectors were generated by varying weight parameters. Performance specifications were used to select a final gain vector. Estimator dynamics were selected and the corresponding gain vectors were computed. Final estimator selection was based on position, commanded rate, and estimator error responses.
