| My research interests revolve around process control and energy
conservation and optimization.
Process Control
We are involved in advanced control studies: adaptive and interacting multivariables,
and statistical controls on various bench-scale processes and on pilot-plant-scale
processes of the Process and Simulation and Control Center. The PSCC is equipped with a
Honeywell TDC-3000 system, which is the state-of-the-art in the distributed control arena.
Current projects also include developing icons for the automatic tuning of PID aided by
neural networks with fuzzy logic on the LabVIEW platform.
Energy Conservation
We are involved in problems which pertain to the control of industrial calciners,
kilns, and dryers, with an emphasis on energy integration, energy conservation, and waste
minimization. Our theoretical and experimental studies encompass flame modeling of
industrial furnaces, investigation of the dynamic behavior of solid materials on the basis
of particle-size distribution, monitoring of overall temperature-profile size
distribution, monitoring of overall temperature profile across the kiln, and
identification of energy losses. We study industrial reactors for waste-energy
minimization using both digital simulations and dynamic control experiments.
Current studies also include mass balance and waste minimization of the
polydimethylsiloxane production process.
