چکیده
کنترل بار در یک رآکتور هسته‌ای به‌دلیل طبیعت دینامیک غیرخطی آن و وابستگی برخی از پارامترها به توان خروجی، حایز اهمیت است. کنترل‌کننده تناسبی- انتگرل‌گیر- مشتق‌گیر (PID) به عنوان یک انتخاب آسان، به‌صورت متداول برای یک کنترل مطمئن مورد توجه قرار دارد. در این پژوهش، چگالی نسبی نوترون در مدل سینتیک نقطه‌ای یک رآکتور آبی تحت فشار (PWR) توسط یک PID بهینه شده با الگوریتم تکامل تفاضلی (DE) فراابتکاری کنترل می‌شود. از شاخص عملکرد انتگرال وزن شده زمانی قدرمطلق خطا (ITAE) برای بهینه‌سازی با این الگوریتم استفاده شده است. نتایج شبیه‌سازی نشان می‌دهند که سیستم کنترل بهینه‌شده توسط الگوریتم DE، کارایی و دقتی مناسب در پاسخ به یک تقاضای بار دارد.

چکیده [English]
The load control of a nuclear reactor is important due to the nonlinear nature of its dynamics and the dependence of some parameters on the output power. the Proportional-Integral-Derivative controller (PID) is commonly regarded as an easy choice for reliable control. In this research, the relative neutron density in the point kinetics model of a Pressurized Water Reactor (PWR) is controlled by an optimized PID with the meta-heuristic Differential Evolution (DE) algorithm. The Integral of Time-Absolute Error (ITAE) performance index has been used for optimization with this algorithm. The simulation results show that the optimized control system with the DE algorithm has the appropriate efficiency and accuracy in response to power demand.
