Project | 01 Detection of Oscillation
Oscillation is generally found in all walks of life. If I talk about from the beginning of the day. Spilling of coffee, an event encountered by most of us in daily life is, in fact, a result of a close match between human gait dynamics and the natural frequency of oscillation of the coffee in the cup. The proposed framework combines both time and frequency information for better oscillation characterization. A key segmentation idea that allows the localization of the oscillating regimes using template matching is used to overcome many of the difficulties with both time and frequency based oscillation characterization approaches. We show that the proposed approached is robust to non-stationarity, intermittency and noise while characterizing oscillations with multiple modes. The power of this approach is demonstrated using data from various disciplines.

Project | 02 Root cause analysis
In industries, interacting control loops are present. Once the disturbance or oscillation enters through any one of the control loops, it directly impacts interacting control loops. Detecting the root cause in such a scenario is very cumbersome especially when the number of loops is large. We developed sophisticated algorithms to successfully detect the root node generating the oscillation from the simulated data.

Project | 03 Detection and Diagnosis of stiction
Static friction commonly known as stiction hinders the path of the control loop to work in an efficient manner. An approach is proposed for detection, diagnosis and quantification of stiction and isolation of the control loop with stiction responsible for inducing oscillation in interacting control loops
