SUV RESURSLARI TAQCHILLIGI SHAROITIDA MAGISTRAL KANALLARDA SUV TAQSIMOTINI MODEL PREDICTIVE CONTROL (MPC) ALGORITMI ORQALI OPTIMALLASHTIRISH
Keywords:
Hozirgi kunda amaliyotda qo‘llanib kelayotgan an’anaviy dispetcherlik yoki operatorlarning empirik tajribasiga asoslangan qoidalar (rule-based scheduling) suv sarfining dinamik tebranishlarini, shimilish (filtratsiya) yo‘qotishlarini hamda ob’ektning chiziqli bo‘lmagan cheklovlarini to‘liq hisobga olishga qodir emas. Ushbu muammoni hal etish uchun jarayonni oldindan bashorat qiluvchi va cheklovlarni inobatga oluvchi Model Predictive Control (MPC) optimal boshqaruv tizimini joriy etish eng samarali ilmiy-amaliy yechim hisoblanadi.Abstract
Global iqlim o‘zgarishi va transchegaraviy suv resurslarining keskin kamayishi sharoitida, Markaziy Osiyo mintaqasida, xususan, O‘zbekistonda chuchuk suv resurslarining 90% dan ortig‘i qishloq xo‘jaligi va sug‘orish ehtiyojlariga yo‘naltirilmoqda. Yirik magistral kanallarda suv taqsimotini real vaqt rejimida (real-time) optimal boshqarish suv resurslari taqchilligining salbiy oqibatlarini yumshatishda strategik ahamiyatga ega.
Yirik sug‘orish kanallarida suv oqimining harakati muvozanatlashmagan, statsionar bo‘lmagan (unsteady) gidravlik qonuniyatlar va dinamik to‘lqinli tebranishlar ostida kechadi. Shlyuz darvozalarining har qanday ko‘rinishdagi o‘zgarishi kanal bo‘ylab gidravlik to‘lqinlar tarqalishiga va quyi b‘eflardagi iste’molchilarning suv ta’minotiga keskin ta’sir ko‘rsatadi.
