Institute of Nuclear and New Energy Technology, Tsinghua University, Beijing, 100084, China

摘要: 基于微小摄动理论,对压水堆堆芯系统的非线性模型进行线性化处理,得到了线性时不变系统模型。利用该模型进行线性二次型高斯(LQG:Linear Quadratic Gaussian)最优控制器设计,并进行了控制系统仿真。结果表明,利用线性化模型对压水堆堆芯系统进行控制系统设计的方法是可行的。

Abstract: Based upon the perturbation theory,a Linear Time-Invariant（LTI） model of the Pressurized Water Reactor is formulated through the linearization of the nonlinear model.A Linear Quadratic Gaussian（LQG） optimal controller is synthesized using the LTI model and simulation experiments are performed.The simulation results show that the methodology of employing the linearized model for control system design is feasible and the control performance is satisfactory.
