Design of parallel compensator and stabilizing controller to mitigate non-minimum phase behaviour of the Czochralski process
Bukhari, Syeda Halima Zahra; Hovd, Morten; Aftab, Muhammad Faisal; Winkler, Jan (Peer reviewed; Journal article, 2020)This paper addresses the design of a parallel compensator and a stabilizing controller for the simplified crystal growth dynamics of the Czochralski (CZ) process, i.e., the process for the production of monocrystalline ... -

Multivariate singular spectrum analysis and detrended fluctuation analysis for plant-wide oscillations denoising
Bounoua, Wahiba; Aftab, Muhammad Faisal (Journal article; Peer reviewed, 2024)Oscillations are considered the most important indicator of poorly performing control loops. However, noise and other disturbances conceal these oscillations, thus making the detection task quite difficult. Furthermore, ... -
Stiction detection in industrial control valves using Poincaré plot-based convolutional neural networks
Bounoua, Wahiba; Aftab, Muhammad Faisal; Omlin, Christian Walter Peter (Peer reviewed; Journal article, 2023)Valve stiction is one of the major causes of poorly performing industrial control loops. Stiction occurs when the static friction exceeds the dynamic friction during a direction change or when the stem is at rest. Recently, ...
