Dr. M. A. A. Shoukat Choudhury received his Bachelor and Master degree in Chemical Engineering from Bangladesh University of Engineering and Technology (BUET), Dhaka, Bangladesh. He obtained his PhD in process control from the University of Alberta, Canada. For his outstanding research performance, he has been honored with several awards namely University of Alberta PhD Dissertation Fellowship, Andrew Stewart Memorial Prize and ISA Educational Foundation Scholarship. He has published more than 25 refereed papers in international journals and conference proceedings in the area of control valve stiction, control performance assessment, condition based monitoring, data compression and plantwide oscillations. He has an international patent on “Methods for Detection and Quantification of Control Valve Stiction”. He is one of the leading experts in the data-based detection and quantification of control valve stiction. He applied his expertise extensively in industrial practice. His research contributions in control valve health monitoring have enjoyed wide applications in chemical, petrochemical, oil & gas, mineral processing, and pulp & paper industries throughout the world. His main research interests include (but not limited to):
- Condition Based Monitoring
- Troubleshooting Plantwide Oscillations
- Diagnosis of Poor Control Performance
- Control Valve Stiction – Modelling, Detection, Quantification and Compensation.
- Control Loop Performance Assessment
- Energy and Environment

A peak in the bicoherence plot shows that the
time series data is nonlinear, which may be an
indication of a fault. |
A consistent band in the wavelet spectrum indicates a persistent oscillation. |

This figure shows that many variables of a plant are oscillating together. What is the root-cause of this oscillation? |
This group shows that these variables have similar oscillation. Probably, they are caused by a single root-cause. |
