Circulating fluidized bed (CFB) combustion systems are increasingly used as superior coal burning systems in power generation due to their higher efficiency and lower emissions. However; because of their non-linearity and complex behavior; it is difficult to build a comprehensive model that incorporates all the system dynamics. In this paper; a mathematical model of the circulating fluidized bed combustion system based on mass and energy conservation equations was successfully extracted. Using these correlations; a state space dynamical model oriented to bed temperature has been obtained based on subspace method. Bed temperature; which influences boiler overall efficiency and the rate of pollutants emission; is one of the most significant parameters in the operation of these types of systems. Having dynamic and parametric uncertainties in the model; a robust control algorithm based on linear matrix inequalities (LMI) have been applied to control the bed temperature by input parameters; i.e. coal feed rate and fluidization velocity. The controller proposed properly sets the temperature to our desired range with a minimum tracking error and minimizes the sensitivity of the closed-loop system to disturbances caused by uncertainties such as change in feeding coal; while the settling time of the system is significantly decreased. © 2007 Elsevier B.V.
