Structured Singular Value Synthesis Based Steam Generator Water Level Controller Design

An uncertainty kinetic model for valve position of feed water to steam generator water level plant was built which can quantitily express parameter perturbation and unmodeled dynamic due to operation condition change of steam generator and feed water pump. Robust controller was designed based on structured singular value synthesis method. Robust stability of the water control system can be guaranteed under parameter perturbation and unmodeled dynamic, and robust performance can be acquired via suitable performance weight function. Simulation results show that good control performances are obtained under all combinations of steam generator operation condition and feed water pump operation condition.
