Inerting Monolithic Catalyst Reactor Temperature Control Based on Fuzzy Control
To restrain high temperature in specific area in monolithic catalyst in oxygen-consumption based inerting sys-tem,promote efficiency and extend service life,a bi-temperature catalyst model is built with Modelica and dynamic simu-lation is proceeded.A Cooling measure based on reversed flow reactor is designed.A fuzzy control system is established according to catalyst temperature character.The operating characteristic of this fuzzy control on reverse-flow under differ-ent condition and reaction tunnel working efficiency under different cooling tunnel distribution is studied.Result shows that this fuzzy control system can restrain high temperature efficiently with good stability.Average reaction rate of single reaction tunnel with one-side and two-side temperature control tunnel rises 1 times and 10 times.Overall conversion rate of fuel steam with temperature control promotes from 10%to 99%.Variance σ2 of membership function obviously influ-ences the control system performance.Greater variance leads to faster response speed and less accuracy.Appropriate σ2 should be chosen according to different inlet condition to obtain best control performance.
