快堆功率和堆芯冷却剂出口温度的线性自抗扰控制

针对快堆控制器具有更快的响应速度和更高的控制精度的需求，分别设计了堆功率和堆芯冷却剂出口温度线性自抗扰控制器（LADRC）。基于快堆中子动力学模型和堆芯热传输模型分别导出了用于控制器设计的相对功率和冷却剂出口温度的2阶非线性模型，并基于导出的模型设计了对应的加入模型信息的线性扩张状态观测器（LESO）。采用所导出的2阶模型的时间尺度参数确定了LESO带宽范围，采用偏差和执行机构动作速度允许范围确定了比例-微分（PD）控制器带宽范围，并据此进行了LADRC参数整定。仿真结果表明，加入模型信息的LESO具有更好的总扰动估计效果，所设计的LADRC均具有较快的响应速度和较高的控制精度，而采用加入模型信息的LESO的LADRC控制性能更优。 

Linear Active Disturbance Rejection Control for Fast Reactor Power and Core Coolant Outlet Temperature

For the?requirements?of fast reactor controller with faster response speed and higher control accuracy, Linear Active Disturbance Rejection Controllers (LADRC) are designed for the reactor power and the core coolant outlet temperature, respectively. Based on the fast reactor neutron dynamics kinetics and the core heat transfer equations, the second order nonlinear models of the relative power and coolant outlet temperature for the controller design are derived, and the corresponding Linear Extended State Observers (LESO) with model information are designed. The range of LESO bandwidth is chosen via the time scale parameters of the derived second order model. The range of PD bandwidth is estimated by the allowable range of deviation and actuator operating speed, and the LADRC parameter tuning is carried out accordingly. The simulation results show that the LESO with model information has better total disturbance estimation capacity. The designed LADRC all are with?faster?control speed and higher precision, and the control performances?of LADRC using LESO with model information are better.
