摘要： 加速器驱动次临界系统(ADS)依靠质子束流与靶作用产生的中子源，来维持反应堆运行。ADS的控制特性与运行策略和传统的压水堆(PWRs)明显不同。本文建立了ADS堆芯的双输入双输出传递函数模型。采用加速器束流和控制棒同时来调节反应堆功率的控制策略，并设计了相应控制器。对ADS动态特性和控制特性进行了仿真，结果表明本文所设计的控制系统能够实现堆芯功率稳定而有效的自动控制。

Abstract： Accelerator driven subcritical system (ADS) produce neutrons depending on proton beams interaction with target, maintaining the reactor operation. The control characteristics and operation strategies of ADS are significantly different from those of the traditional Pressurized Water Reactors (PWRs). In this paper, the double-input-double-output transfer function model of the ADS core was established, both accelerator beam and control rod is adopted to adjust reactor power simultaneously, and the controllers are designed for this control strategy. The dynamic characteristics and control characteristics of ADS are simulated, and the results show that the designed control system could provide stable and effective automatic control of the core power.
