Nonlinear systems with disturbances: analysis, controller design and tradeoffs. A range of classical asymptotic methods (averaging, singular perturbations and slowly varying techniques) have been recently generalized to deal with nonlinear systems with disturbances. The goal of this proposal is the activation of these methods in analysis, controller design and understanding the design tradeoffs of nonlinear system with disturbances. Application areas are in adaptive, vibrational and gain schedul ....Nonlinear systems with disturbances: analysis, controller design and tradeoffs.

Tools for analysis and controller design for nonlinear systems with disturbances. Control engineers often need to deal with nonlinear systems with disturbances (NSD). Analysis and controller design for NSD requires the use of a range of different tools including singular perturbations, averaging, slowly varying systems methods and large scale systems methods. However, often these tools are inadequate as they are only applicable to systems without disturbances. We propose to extend these tools to ....Tools for analysis and controller design for nonlinear systems with disturbances. Control engineers often need to deal with nonlinear systems with disturbances (NSD). Analysis and controller design for NSD requires the use of a range of different tools including singular perturbations, averaging, slowly varying systems methods and large scale systems methods. However, often these tools are inadequate as they are only applicable to systems without disturbances. We propose to extend these tools to NSD and apply them to a range of problems arising in analysis and controller design for NSD. These applications include vibrational control, gain scheduling, H-infinity control and adaptive control.Read moreRead less

Imaging circumstellar matter at high resolution. Within contemporary astrophysics there is a particular fascination with matter in near-stellar environments. Studies of stellar and planetary systems from formation through to eventual destruction entail observation of material, principally dust and gas, playing their parts on a very remote stage. A new generation of telescopes, known as interferometers, deliver extremely high resolutions enabling our first direct glimpses of these phenomena. Here ....Imaging circumstellar matter at high resolution. Within contemporary astrophysics there is a particular fascination with matter in near-stellar environments. Studies of stellar and planetary systems from formation through to eventual destruction entail observation of material, principally dust and gas, playing their parts on a very remote stage. A new generation of telescopes, known as interferometers, deliver extremely high resolutions enabling our first direct glimpses of these phenomena. Here I propose using a number of these devices in concert in order to dramatically enhance their scientific payoff. In addition to enabling unique studies of stellar systems, new techniques for merging disparate data into powerful combined forms will be devised.Read moreRead less
