Title: H∞ Reduced Order Control of a Thermal Plant
Keywords: Hankel Singular values,H∞ theory,reduced order controller

Abstract: The current paper investigates the possibility of H∞ controller order reduction for a simple dynamic plants, which are predominand in the industry. A design procedure is carried out for a thermal plant model, received by system identification. Two full order controllers with integral part are obtained having series and parallel form. A mixed S/KS sensitivity structure is employed. Using Hankel singular values additional 5 reduced order controllers are obtained. Finally based on reduced plant model 4 new controllers are obtained. All control algorithms are implemented in digital form based on discrete state space equations, on a Programmable Logic Controller. Simple programs are developed for matrix addition and multiplication based on user defined PLC type. Additionally some programs are implemented for matrix transfer between a MATLAB client and SCADA OPC server. Experiments are conducted with a real plant.
