This paper uses a nonlinear model of the pressure and flow dynamics inside a gas header to obtain the optimal pressure measurement location for buffering control. The nonlinear model is derived from governing equations using the spectral element method (SEM). The pressure states at the collocation points are estimated using an extended Kalman filter (EKF) and subsequently used as potential measuring locations. A staggered regulatory pressure control scheme is used to evaluate the closed-loop performance of the objective function in a self-optimising control (SOC) framework. It is found that there are opposing goals in the optimisation scheme and that the final pressure location selection is dependent on the economic importance of these goals. The economic goals which cause opposing control objectives include minimising flaring, providing down-stream consumer stability, and limiting expensive supplier use.

本文使用集气管内压力和流动动力学的非线性模型来获得用于缓冲控制的最佳压力测量位置。使用频谱元素法（SEM）从控制方程中导出非线性模型。使用扩展的卡尔曼滤波器（EKF）估计并置点的压力状态，然后将其用作潜在的测量位置。交错的调节压力控制方案用于在自优化控制（SOC）框架中评估目标函数的闭环性能。发现优化方案中存在相反的目标，并且最终压力位置的选择取决于这些目标的经济重要性。导致相反控制目标的经济目标包括将火炬燃烧最小化，
