چکیده

کنترلر PID مرتبه کسری (FOPID) تعمیم یافته کنترلر PID استاندارد با استفاده از حسابان کسری می‌باشد. در مقایسه با کنترلر PID استاندارد، دو متغیر قابل تنظیم "مشتق کسری" و "انتگرال کسری" به کنترلرPID  اضافه می‌شوند. سیستم سه مخزن یک فرآیند چند متغیره غیر خطی است که یک نمونه اولیه خوب از فرآیندهای صنعتی می‌باشد. الگوریتم بهینه‌سازی فاخته (COA) که اخیراً معرفی شده است عملکرد خوبی در مسائل بهینه‌سازی نشان داده است. در این تحقیق الگوریتم بهینه‌سازی فاخته بهبود یافته (ICOA) ارائه شده است. هدف از این مقاله مقایسه کنترلرهای مختلف با الگوریتم بهینه‌سازی فاخته بهبود یافته برای سیستم سه مخزن تنظیم شده است. بدین منظور عملکرد کنترلر FOPID بهینه شده با کنترلرهای دیگر، الگوریتم ژنتیک (GA)، بهینه‌سازی ازدحام ذرات (PSO)، الگوریتم بهینه‌سازی فاخته (COA) و الگوریتم رقابت استعماری (ICA) مقایسه می‌شود

چکیده [English]

Fractional-order PID (FOPID) controller is a generalization of standard PID controller using fractional calculus. Compared with the Standard  PID controller, two adjustable variables “differential order” and “integral order” are added to the PID controller.Three tank system is a nonlinear multivariable process that is a good prototype of chemical industrial processes. Cuckoo Optimization Algorithm (COA), that was recently introduced has shown its good performance in optimization problems. In this study, Improved Cuckoo Optimization Algorithm (ICOA) has been presented. The aim of the paper is to compare different controllers tuned with a Improved Cuckoo Optimization Algorithm (ICOA) for Three Tank System. In order to compare the performance of the optimized FOPID controller with other controllers, Genetic Algorithm(GA), Particle swarm optimization (PSO), Cuckoo Optimization Algorithm (COA) and Imperialist Competitive Algorithm (ICA).
