Abstract

Fluid flow networks (FFNs) widely exist in water/gas distribution, mine ventilation and other engineering systems. FFN control is crucial for the safe, stable and efficient operation of FFNs. In this paper, a simpler minimal representation of the nonlinear FFN model is given. Based on this simpler model, the strict dissipative feature of FNNs is revealed. Moreover, an adaptive decentralized FFN stabilizer that takes a proportional integral (PI) form is proposed. This stabilizer not only provides closed-loop stability but also does not need the values of network physical or hydraulic parameters. Due to its neat form, this new stabilizer can be easily implemented in the practical engineering. Finally, numerical simulation results show the feasibility of this newly-built FFN stabilizer.
