State estimation of International Space Station centrifuge rotor with incomplete knowledge of disturbance inputs
This thesis develops a state estimation algorithm for the Centrifuge Rotor (CR) system where only relative measurements are available with limited knowledge of both rotor imbalance disturbances and International Space ...
Dynamic response of multi-degree of freedom structure with sliding isolation system and uplift
In this study the two dimensional dynamic response of a Multi Degree of Freedom (MDOF) sliding isolated structure permitted to uplift is studied. The MDOF superstructure is supported by two sets of sliding bearings situated ...
Repetitive control of hysteretic systems using robust H-infinity controller
Unique properties of smart materials have enabled them to successfully replace conventional actuators and sensors. However, their effectiveness and applicability in control is hindered due to the presence of inherent ...
