Adaptive control of a nuclear power plant is considered for the case of load-following operation in the pressurized water reactors(PWR). In order to perform the steady state and load-following operation in PWR plant, 11th order nonlinear model for the reactor and steam generator is derived, and linearized by Taylor series at 50[%] of full power. Adaptive control system of the PWR plant is designed by adaptive model following control with signal synthesis adaptation of Liapunov. This system proposed in this paper has a fast and good response under the step change of demanded power. Simulation results indicate that it is quite possible to obtain adaptive control system of the PWR plant under load-following operation.

Self-tuning control is the one of the various useful methods to control the system of which dynamic characteristics are varying during continuing operation. Thus, self-tuning adaptive control of a pressurized water reacter (PWR) is considered to adapt the disturbances, the parameter variations, and a change of demanded load. Low-order (2nd) model of the nuclear/thermal part of a PWR is derived by approximation to design the self-tuning controller of a nuclear reactor. For online identification and minimal computation, the extended least square method is used to estimates the parameters of a nuclear reactor. It is confirmed that the self-tuning adaptive controller by the pole-placement proposed in this paper has a good convergence properly, a small error of parameter estimation, and a good response of a change of demanded load. Simulation results indicate that it is quite possible to design and apply the self-tuning adaptive control to the real PWR plant.
