Abstract

This brief focuses on the control of steam power plants using a nonlinear model-based controller with deadtime compensation that is efficient for narrow and wide power demand ranges. The variables to be controlled are the boiler pressure and the power generation. The challenge in controlling this system lies in the ability to overcome the strong nonlinear interactions that a power plant exhibits as well as the deadtime associated with fuel flow adjustment. The derived controller was tested for set point tracking as well as disturbance rejection cases, showing excellent performance and robustness.
