摘　　要：采用传统比例-积分-微分(PID)控制器开展堆芯功率控制,控制过程中存在超调量大、调节时间长的问题。为解决这一问题,基于堆芯传递函数模型,采用T-S型模糊规则对比例-微分(PD)控制器、PID控制器、模糊控制器进行加权及切换,设计T-S型模糊切换控制器。以铅冷快堆堆芯功率控制为例,建立堆芯功率T-S型模糊切换控制系统,开展堆芯相对功率设定值阶跃、堆芯冷却剂进口温度扰动仿真。结果表明,基于堆芯传递函数模型设计的T-S型模糊切换控制器可以实现对堆芯功率的良好控制。The traditional PID controller is used to control the core power,which has the problems of large overshoot and long regulating time in the control process.In order to solve this problem,based on the core transfer function model,the PD controller,the PID controller and the fuzzy controller are weighted and switched by T-S fuzzy rules,and T-S fuzzy switching controller is designed.Taking the core power control of a lead cooled fast reactor as an example,a T-S fuzzy switching control system of the core power is established to simulate the relative power setpoint value step and the core inlet coolant temperature disturbance.The results show that the T-S fuzzy switching controller designed based on the core transfer function model can achieve a good control of the core power.
