Abstract
Due to the pressurized water reactor(PWR)has the features of highly nonlinearity and uncertainty,an adap-tive guaranteed cost controller for load-following is proposed in this paper.At first,on the basis of the point reactor model and the introduction of an integral item of the power level error,the augmented state space model of the reactor system is derived. Then the polytopic linear parameter varying(LPV)model is established combining with the LPV theory. The control input generated by the proposed controller is constituted by the state feedback control and the uncertainty com-pensation. By polytopic model theory and linear matrix inequality techniques,a gain-scheduled state feedback controller which provides globally asymptotic closed-loop stability is designed. Utilizing the Lyapunov theory and guaranteed cost control theory,an adaptive control law for uncertainty is developed.Numerical simulation results illustrate the high control performance of the proposed method in load-following operation.关键词
