Output Feedback PD Power-Level Control for Modular High Temperature Gas-Cooled Reactors
Due to its inherent safety feature,the modular high temperature gas-cooled reactor(MHTGR)has been seen as one of the best candidates in building next generation nuclear plants(NGNPs).Since the MHTGR dynamics has high nonlinearity,it is necessary to develop nonlinear power-level controller which is not only beneficial to the safe,stable,efficient and autonomous operation of the MHTGR but also easy to be implemented practically.In this paper,based on the concept of shifted-ectropy and the physically-based control design approach,it is proved theoretically that the simple proportional-differential(PD)output-feedback power-level control provides globally asymptotic closed-loop stability.Numerical simulation results verify the theoretical results and show the influence of the controller parameters to the dynamic response.
