Abstract
Constrained, spectral, independent component analysis of perturbed controller output data is proposed to isolate multiple sources of plant-wide oscillations. The technique is described and applied to data pertaining to a simulated case study and to real data obtained from an industrial chemical plant. Results demonstrate its ability to isolate the sources of multiple oscillations at the loop level.
