In this paper we consider the problem of localizing inputs in swing dynamic models of large power system networks in the form of forced oscillations with unknown amplitude and frequency. Such harmonic oscillations commonly result from internal failures of control actuators in synchronous machines, and are particularly dangerous because their frequency often lies in the range of the inter-area o...

Energy shaping and passivity-based control designs have proven to be effective in solving control problems for underactuated mechanical systems. In recent works, Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC) has been successfully applied to open loop conservative models, i.e. with no physical damping (e.g., friction) present. In a number of cases, in particular when I...

This semester, as an undergraduate research project, I worked with my mentor on coding and analyzing an algorithm for reducing second order MIMO system. The algorithm was taken from the article " Interpolatory Projection Methods for Structure-Preserving Model Reduction " by C. Beattie and S. Gugercin. It proved to be fairly challenging project for me, both from a mathematical and a programming ...

In this paper we study formation control of a network of communicating mobile agents with double integrator dynamics. All agents run a consensus algorithm, several leader agents are further subject to an external input. We put this problem in a control theoretical framework and show that the controllability of the entire system via external control input depends only on the controllability of t...

This note states necessary and sufficient conditions for the existence of a linear state feedback controller such that a second-order bilinear system has a globally asymptotically stable closed loop. A suitable controller is constructed for each system which satisfies the conditions. Comments Copyright 1983 IEEE. Reprinted from IEEE Transactions on Automatic Control, Volume AC-28, Issue 10, Oct...
