Abstract
In this chapter a model-based oscillation root-cause detection and quantification approach is presented. The objective of this methodology is to devise a strategy to make the diagnosis applicable to most practical situations encountered in industry by considering the presence of multiple faults occurring simultaneously. Power spectral density (PSD) and auto-correlation function (ACF) based oscillation detection method (described in Chap. 4) followed by a model-based approach for identifying and quantifying the root-cause of the oscillations is presented in this chapter. The application of each component of the algorithm is described with appropriate illustrative examples. Overall methodology is validated on simulation case studies involving various cases of stiction, poor controller tuning, and external disturbances.
