Abstract

In this study, a transient control method is proposed through the generation of an alternative transient in pipe network systems. A control-oriented transient analysis is performed to achieve transient control in the context of linear independence. The relationship between pressure head and discharge are incorporated into a control-oriented impedance matrix and the response function is formulated from either the discharge or pressure head impulse to either a point-scale or integrated section pressure response, or their combination. A surge control scheme is proposed by integrating a metaheuristic algorithm into the superposition platform of the response functions. Application examples demonstrate that the proposed method is a potential platform for a centralized pressure management system in a pipe network. The effectiveness of the proposed scheme in an actual system is confirmed by the method’s feasible multi-objective formulation, efficient computational cost for real-time operation, and robustness against pressure noise in commercially available sensors.
