On Integral Quadratic Constraint Theory and Robust Control of Unmanned Aircraft Systems
… analysis of uncertain systems where the nominal plant and the IQC multiplier are linear time-varying systems and the nominal plant may have a non-zero initial condition. When the nominal plant and the IQC multiplier are eventually periodic, robustness analysis can be accomplished by …

Robust low-order control of flexible joint manipulators
… represented as the structured uncertainty of the nominal plant. The $H\sb{\infty}$-norm approach is then utilized to design a robust state feedback controller to stabilize the linear system and to give a specified bound on the disturbance rejection of the closed-loop system with enough robustness …

X-ray microscope performance enhancement through control architecture change
The goal of this thesis is to apply control algorithms to improve the performance of nanopositioning devices used on the beamline in Advanced Photon Source (APS) at Argonne National Laboratory (ANL). A prototype device, better known as the Early User Instrument (EUI) was the subject of this work. …
