摘要:: [目的]掺氢天然气管道输送是实现氢能高效经济输送的重要方式。对掺氢天然气管道中掺氢比例精准控制，能有效保障下游用氢端的稳定性，为“氢进万家”工程的推进保驾护航。[方法]为此，采用系统辨识方法建立数学模型，基于Smith预估补偿与模糊控制规则，结合智能控制与比例积分微分（Proportional Integral Differential,PID）技术，构建了Smith-Fuzzy PID控制器，发展了基于模糊PID控制的天然气管道掺氢比例精准调控系统。通过对Smith预估器的参数调整，提前估计系统的滞后效应，修正滞后环节带来的偏差，更快响应控制输入变化对滞后环节的补偿，提高掺氢比例调控系统的响应速度及稳定性；通过模糊控制策略对数据进行模糊处理可减少计算量，快速获取最优参数组合，进一步提高了系统的响应速度及稳定性。采用Simulink仿真技术，通过经验整定法得到输入参数比例系数KP、积分系数KI及微分系数KD，对比分析了传统PID控制、Smith-PID控制、Smith-Fuzzy PID控制的调节时间、响应时间及超调量等参数的变化规律。在天然气管道掺氢比例精准调控试验平台上开展掺氢比5%、10%、15%、20%的实验，验证了该控制系统的掺混比例调控精度。[结果]与传统PID控制、Smith-PID控制相比，Smith-Fuzzy PID控制在调节时间、响应时间、超调量上比传统PID控制提高了79.9%、70%、82.5%，比Smith-PID控制提高了44%、50%、77.9%。Smith-Fuzzy PID控制在不同的掺氢比下平均掺氢精度均控制在±1.5%的范围内。[结论]基于Smith-Fuzzy PID控制的掺氢比例精准调控系统适用于天然气掺氢这类非线性、滞后性的复杂工况，可满足天然气管道掺氢比例控制对快速响应、稳定输出及精准控制的综合要求，研究结果可为保证掺氢天然气管道安全输送与终端安全利用提供技术支撑。

Abstract:: [Objective] Hydrogen-blended natural gas pipeline transportation is an important method for achieving efficient and economical hydrogen energy delivery. Precise control of the hydrogen blending ratio in hydrogen-blended natural gas pipelines can effectively ensure the stability of downstream hydrogen usage and safeguard the advancement of the "Hydrogen into Homes" project. [Methods] To this end, a mathematical model was established using system identification methods. By integrating Smith predictive compensation, fuzzy control rules, intelligent control, and Proportional Integral Differential (PID) technology, a Smith-Fuzzy PID controller was constructed, and a precision regulation system for hydrogen blending ratios in natural gas pipelines based on fuzzy PID control was developed. Through parameter adjustment of the Smith predictor, the system's lag effect was estimated in advance to correct deviations caused by lagging processes, enabling faster compensation for control input changes and improving the response speed and stability of the hydrogen blending ratio regulation system. The fuzzy control strategy reduced computational load by fuzzifying data, allowing rapid acquisition of optimal parameter combinations and further enhancing system responsiveness and stability. Simulink simulation technology was employed to obtain proportional coefficient KP, integral coefficient KI, and differential coefficient KD via empirical tuning. Comparative analyses were conducted on parameters such as settling time, response time, and overshoot under traditional PID control, Smith-PID control, and Smith-Fuzzy PID control. Experiments with hydrogen blending ratios of 5%, 10%, 15%, and 20% were performed on a natural gas pipeline hydrogen blending ratio precision regulation platform to validate the system’s control accuracy. [Results] Results show that compared to traditional PID control and Smith-PID control, the Smith-Fuzzy PID control improved settling time, response time, and overshoot by 79.9%, 70%, and 82.5%, respectively, over traditional PID control, and by 44%, 50%, and 77.9% over Smith-PID control. The average hydrogen blending accuracy of Smith-Fuzzy PID control across different hydrogen blending ratios remained within ±1.5%. [Conclusion] The Smith-Fuzzy PID-based precision hydrogen blending ratio regulation system is suitable for complex nonlinear and lag-dominant scenarios like natural gas hydrogen blending. It meets the comprehensive requirements of rapid response, stable output, and precise control for hydrogen blending ratio regulation in natural gas pipelines. The findings provide technical support for ensuring the safe transportation of hydrogen-blended natural gas pipelines and the secure utilization of terminal applications.
