Robust Optimal Gain Scheduling Controller for Nuclear Reactors

Nuclear power reactors are, in nature nonlinear and time varying. These characteristics must b e considered, if large power variations occur in their working regime. In this paper a robust optimal gain scheduling controller for regulating the power of a nuclear reactor has been designed and simulated. The proposed controller is capable of regulating power levels in a wide power range (10% to 100% power levels). The controller achieves a fast and good transient response. The simulation results show that the proposed controller outperforms the fixed optimal control recently cited in the literature for nuclear power plants.
