چکیده

این پژوهش، به طراحی ساختار کنترلی با استفاده از کنترل‌کننده تناسبی انتگرالی همراه با پارامتر جبران‌ساز در فضای حالت غیرکمینه (NMSS) می‌پردازد. شناسایی سیستم به روشRIVID از طریق Simulink نرم‌افزار متلب و با استفاده از جعبه‌ابزارCaptain جهت به دست آوردن مدل سیستم صورت گرفته است. سپس ساختار کنترلی چند ورودی-چند خروجی (MIMO) در حالت مربعی برای یک سیستم 8×8 توسعه داده شد تا کیفیت محصولات جانبی حفظ گردد. در ادامه بهینه‌سازی مصرف انرژی فرآیند، با تعریف تابع هدفی بر مبنای کمینه نمودن میزان هزینه انرژی انجام شد. بر مبنای نتایج به‌دست‌آمده ضمن حفظ کیفیت محصولات، بخار ورودی به برج اصلی 19/8 درصد، بخار ورودی به عریان‌ساز گازوئیل 10/255 درصد، بار حرارتی ورودی به عریان ساز نفتا 3/83 درصد، بار حرارتی ورودی به عریان ساز ‌نفت‌سفید 3/41 درصد کاهش یافتند و تنها بار حرارتی کوره به میزان 0/135درصد افزایش یافت و در نهایت میزان هزینه انرژی مصرفی 8/5 درصد کاهش یافت.

چکیده [English]

This research, presents control structure design using non-minimal state space proportional-integral plus (PIP-NMSS). The system identified by RIVID method using SIMULINK of MATLAB by applying CAPTAIN Toolbox in order to achieve system model. The multi input-multi output (MIMO) control structure developed for 8×8 square state system to keep side products quality. The energy cost optimization was done by defining of energy consumption as objective function. The results show that inlet vapor to main column has been reduced by 19.8%, vapor inlet of gasoil stripper column has been reduced by 10.22%, heat duty of naphtha stripper column has been reduced by 3.83% and heat duty of kerosene stripper column has been reduced by 3.41%, while 0.135% increase observed in furnace heat duty. Based on the results energy cost has been reduced by %8.5, whilst kept quality products.
