The　municipal　solid　waste　incineration　(MSWI)　process　is　subject　to　factors　such　as　strong　nonlinearity,　changes　in　working　conditions,　and　difficulty　using　precise　mathematical　models　to　describe　complex　characteristics,　resulting　in　the　fact　that　traditional　PID　control　cannot　effectively　control　the　amount　of　oxygen　content　of　the　flue　gas.　The　oxygen　content　of　the　flue　gas　is　one　of　the　key　factors　in　the　effect　of　municipal　solid　waste　incineration　(MSWI),　and　either　too　high　or　too　low　oxygen　content　will　affect　whether　the　incineration　and　safety　production　can　be　effectively　carried　out.　This　paper　proposes　a　hybrid　intelligent　closed-loop　control　method　consisting　of　four　parts:　the　pre-set　module,　the　oxygen　content　of　the　flue　gas　forecasting　model,　the　forecasting　compensator,　and　the　feedback　compensator.　Finally,　the　experiments　are　conducted　to　us　the　field　operating　data　from　a　large　MSWI　plant.　The　results　showed　that,　compared　with　the　traditional　method,　the　control　accuracy　of　the　oxygen　content　of　the　flue　gas　improved.　©　2024　IEEE.
