Research Abstract

The purpose of this study is 1) to develop a controller design method based on the notion of gamma-passivity and 2) to validate the gamma-passivity control for the vibration of large flexible space structures. The feature of the method is to enable us to specify gain and phase margins of control systems as well as to guarantee the robust stability for usual unstructured uncertainty. The H-infinity control which is known as a standard design method for robust control systems is pointed out not to be specify desired gain and phase margins. Therefore, the method proposed in this study is more flexible than the H-infinity control. An experimental validation of the method has been made for a flexible structure control. The aim of the control is to suppress the vibration and to regulate the angular position of the structure. The difficulty of the control is that the movement of the angular position stimulates high-frequency vibrations of the structure. Consequently, there is a tradeoff between the performance of settlement of the position and vibration. Toward such difficulty, the control system should be designed to improve the regulation performance and to guarantee the robust stability for unmodelled high-frequency dynamics. The gamma-passivity control, more generally, a control based on the notion of dissipativity has been shown to be effective the requirement mentioned above, theoretically and experimentally.
