Dynamic System Identification Toolbox Developed at the Pacific Northwest National Laboratory with contributions from other government entities and universities.
The DSI Toolbox provides unique capabilities in the analysis and control of large dynamic systems. It is designed to run with MATLAB, providing flexibility in using, tailoring, and integrating the functionality in combination with other tools. Its functions include data format conversion, data merging, data filtering, data batch plotting, Fourier analysis, Prony analysis, and ModeMeter.
The DSI Toolbox is primarily oriented toward the analysis of phasor measurement unit-based information. Please visit the website for the North American SynchroPhasor Initiative (NASPI - http://www.naspi.org) for more details on phasor measurement unit analysis and other tools.
