MAQOLA ANNOTATSIYASI

Maqolada chiziqli bo‘lmagan dinamik tizimlar uchun PID-turli noqat’iy-mantiqiy rostlagichni ishlab chiqish vazifasi ko‘rib chiqilgan. Rostlagich tuzilishini dekompoziciyalarga ajratish orqali soddalashtirish muhim xususiyatlardan biridir. Eng sodda variantda uchta noqat’iy rostlagich bitta kirish, bitta chiqish va alohida qoida bazalari bilan ishlatiladi. Noqat'iy rostlagichlarning parametrlari genetik algoritm yordamida optimallashtirilgan. Chiziqli bo‘lmagan dinamik obyekt uchun ikki bosqichli rostlagichni sozlash sxemasi taklif etiladi. Birinchi bosqichda chiziqli PID-rostlagichni sozlash uchun genetik algoritm qo‘llaniladi, olingan koeffitsientlar noqat’iy PID-rostlagichning har bir kanalining chiqishida ishlatiladi. Ikkinchi bosqichda, genetik algoritmdan foydalanib sun’iy neyron tarmog‘i asosida amalga oshiriladigan har bir kanal uchun chiziqli bo‘lmagan o‘zgartirish funkciyasi hosil bo‘ladi. Matlab dasturi yordamida boshqarish algoritmi tekshirilgan va sinovdan o‘tkazildi. Olingan natijalar an’anaviy rostlagichlarga qaraganda o‘tish jarayonning xususiyatlari sezilarli yaxshilanishini ko‘rsatadi.
