INTEGRATED MODELING AND CONTROL FOR THE LARGE SPACECRAFT CONTROL LABORATORY EXPERIMENT FACILITY

A software package which integrates model reduction and controller des ign is applied to design controllers for the Jet Propulsion Laboratory Large Spacecraft Control Laboratory experiment facility. Modal cost a nalysis is used for the model reduction, and various output covariance constraints are guaranteed by the controller design. The main motivat ion is to find the controller with the best performance with respect t o output covariances. It is shown that by iterating on the reduced-ord er design model, the controller designed does have better performance than that obtained with the first model reduction, demonstrating an ef fective strategy for integrating modeling and control design.
