摘要
针对堆芯功率的非线性控制问题,提出了一种自耦PID(SCPID)功率控制方法。该方法将系统内部所有已知或未知复杂因素及外部扰动定义为一个总扰动,建立了以总扰动为激励的受控误差系统,进而设计了基于SCPID控制理论的堆芯功率控制系统,并在复频域对闭环控制系统的稳定性进行严格的数学分析和证明。结果表明:与其他方法相比,SCPID控制方法简单高效,在堆芯功率系统控制领域具有实际应用价值。
To solve the control problems of nonlinear control of reactor core power,a self-coupling proportional-integral-differential(SCPID)control method was proposed.In this method,all the known or unknown complex factors and external disturbances in the system were defined as a total disturbance,and the controlled error system was established with the total disturbance as the excitation.Then,the core power control system based on SCPID control theory was designed,and the stability of the closed-loop control system in the complex frequency domain was rigorously analyzed and proved.Results show that compared with other methods,the control method of SCPID is simple and efficient,and has practical application value in the field of reactor core power system control.
