Strelkani besh simli boshqarish sxemasini tahlil qilish
Ishdan maqsad: Strelkani beshsimli boshqarish sxemasi misolida quyidagilarni o‘rganish:
• «Strelkalarni boshqarish sxemalarini qurish tamoyillari» mavzusidagi nazariy ma’lumotlarni mustahkamlash;
• Ko‘rsatilgan tamoyillarni amalga oshirish usullarini o‘rganish;
• Strelkani boshqarish qurilmasini ishlash algoritmini o‘rganish;
• Sxemada tez tez uchrab turadigan nosozliklar paydo bo‘lganda strelkani boshqarish qurilmasini ishlashini tadqiqot etish.
