摘　　要：在核电工程中,精确的时间控制对于确保反应堆的安全运行和数据的准确记录至关重要。例如,在核电站的控制系统中,时间激活误差可能会影响反应堆的控制信号,进而影响反应堆的稳定性和安全性。因此,该文提出了一种基于模糊PID的嵌入式智能电表检定装置时间激活误差自动控制方法。首先,通过分析电表检定装置时间激活误差的来源,建立误差子模型,并通过叠加拟合得到误差综合模型,以明确检定装置时间激活误差与误差源之间的关系。然后,结合模糊PID方法针对检定装置的时间激活误差设计控制器。最后,引入反馈机制对控制器的控制参数进行调整与优化,得到最优控制参数,以此对检定装置时间激活误差进行控制,得到校正后的测量时间,完成检定装置时间激活误差的校正。实验结果表明,利用所提方法对检定装置时间激活误差进行自动控制后,误差漂移较小,控制性能更加优异。In nuclear power engineering,precise time control is crucial for ensuring the safe operation of the reactor and accurate recording of data.For example,in the control system of a nuclear power plant,time activation errors may affect the control signal of the reactor,thereby affecting the stability and safety of the reactor.Therefore,this article proposes an automatic control method for time activation error of an embedded intelligent meter calibration device based on fuzzy PID.Firstly,by analyzing the sources of time activation errors in the electric meter calibration device,an error sub model is established,and a comprehensive error model is obtained through superposition fitting to clarify the relationship between the time activation error of the calibration device and the error source.Then,combined with the fuzzy PID method,a controller is designed for the time activation error of the calibration device.Finally,a feedback mechanism is introduced to adjust and optimize the control parameters of the controller,obtaining the optimal control parameters.This is used to control the time activation error of the calibration device,obtain the corrected measurement time,and complete the calibration of the time activation error of the calibration device.The experimental results show that using the proposed method to automatically control the time activation error of the calibration device results in smaller error drift and better control performance.
