چکیده | ||
چکیده: در این مقاله به بررسی و کنترل سکوهای پایهکششی (TLP[i]) که یکی از متداولترین سیستمهای توربین بادی شناور فراساحلی است پرداخته شده است. مهمترین بحثی که در نصب این قبیل توربینها وجود دارد، نحوه کنترل و شناور ساختن آنها بر روی آب است. بهمنظور طراحی کنترلکننده برای سیستم مذکور، ابتدا یک تابع غیرخطی بهعنوان کاندیدای لیاپانوف تعریف میشود. سپس ثابت میشود که سیستم TLP با تأخیر چندگانه متغیر با زمان، در حضور نیروی خارجی پایدار بوده و با کمک ابزار نامساویهای ماتریسی خطی (LMI[ii]) به طراحی کنترلکننده پرداخته میشود. درنهایت با شبیهسازی در محیط Simulink-MATLAB دیده میشود که تمامی متغیرهای حالت سیستم بهصورت مجانبی پایدار بوده و در حالت تنظیمکنندگی[iii] بهسمت صفر همگرا میشوند. | ||
