Modelling of Nuclear Reactor and Power Control by Extended Frequency Method

The controller for the control of nuclear reactor power is designed. The reactor is modelled by using the three dimensional reactor design code of MASTER. From the relation of the input and output of the reactor code, the reactor dynamic model is derived by the system identification method. With this model, a controller is designed by the extended frequency response method. Since this method has the same theoretical background as the classical method, all the existing design techniques of the classical method can be used directly. The designed controller is simple, and gives a sufficient robustness with good performance
