英文摘要： In this proposition, the nonlinear model predictive control theory and algorithm will be researched on a class of nonlinear dynamic systems that can be represented by high-temperature gas-cooled reactor(HTGR) nuclear power plant,and can be described as the Hessenberg differential-algebraic equations (DAEs).The corresponding optimal control problem for HTGR nuclear power plant with load changing will be studied. First, the structure and formulation of nonlinear model predictive controller(NMPC) based on the Hessenberg differential-algebraic equations model are studied, in order to achieve stability requirements. Then, the numerical solution of nonlinear model predictive controller will be studied based on the simultaneous method, the compatibility, convergence, convergence speed and stability of the numerical difference algorithm will be analyzed, and the research on control quality, system stability and robustness of closed-loop system will be performed. Last, the automatic load changing control strategy based on nonlinear model predictive control will be verified in the semi-physical simulation platform of HTGR nuclear power plant. The prototype software of nonlinear model predictive controller will be developed, and the control performance will be analyzed.
