Tzouanas earned a diploma in chemical engineering from Aristotle University, a master's of science degree in chemical engineering/process control from the University of Alberta, and a doctorate of philosophy degree in chemical engineering/process control from Lehigh University. His research interests focus on process control systems, process modeling, and simulation. His industrial professional experience includes management and technical positions. He is a member of AIChE.
Design and Control of an Air Heater Process AbstractThe paper is concerned with the design of an air heater and experimental evaluation of feedbackand feed forward control structures to achieve a desired heater outlet temperature by adjustingthe heat load in the presence of a measured air flow disturbance. It was found that a combinedfeedback/feed forward control structure outperforms the simpler feedback only control structure.The impact of variable time delays on the control performance is demonstrated and addressedusing a Smith predictor. This experimental study entails the design of the air heater andassociated instrumentation, real time data acquisition and control in LABView, processmodeling, controller design, and evaluation of the performance of different control structures in aclosed loop manner. This work was performed as partial fulfillment of the requirements of theSenior Capstone Project course in controls and instrumentation. Student experiences aresummarized and the need for effective project management methods is emphasized.Note: this student led paper is to be considered for poster presentation.
