摘　　要：结合１０ＭＷ高温气冷实验堆（ＨＴＲ－１０）数学模型的推导和控制系统的设计，介绍解决大延迟系统控制的Ｆｕｚｚｙ－Ｓｍｉｔｈ预估控制器。热工动特性中，堆芯部分用集中参数近似，冷却剂用分布参数处理；蒸汽发生器分为预热段、蒸发段、过热段，建立高温气冷堆的数学模型。扰动量为从额定核功率１００％减小到３０％，调节氦风机的转速和给水流量使主蒸汽出口温度跟随给定值。仿真结果表明，Ｆｕｚｚｙ－Ｓｍｉｔｈ预估控制器兼顾了Ｆｕｚｚｙ控制和Ｓｍｉｔｈ预估控制器的优点，既对延迟特性有较好的补偿作用，又对被控对象参数变化有较强的适应能力，适合于高温气冷堆控制系统设计。The Fuzzy Smith pre estimate controller to solve the control of the big delay system is developed in this paper, accompanyed with the development of the mathematical model of the 10 MW high temperature gas cooled test reactor (HTR 10) and the design of its control system. The simulation results show the Fuzzy Smith pre estimate controller has the advantages of both fuzzy control and Smith pre estimate controller; it has better compensation to the delay and better adaptability to the parameter change of the control object. So it is applicable to the design of the control system for the high temperature gas cooled reactor.
