Robust decentralized control for a boiler — turbine unit

Performance control of a boiler-turbine unit is of great importance due to demands on the economical operations of power plants and environmental awareness. In this paper, a robust decentralized control of nonlinear multi input-multi output (MIMO) model of a utility boiler-turbine unit is designed. Drum pressure, generator electric output and drum water level (as the output variables) are controlled by manipulation of valves position for fuel, feedwater and steam flows.
