چکیده

در این مقاله کنترل پرواز آرایشمند فضاپیماها با به کارگیری کنترل هیبریدی PID-FUZZY مورد بررسی قرار گرفته است. انحراف و تغییر مسیر سیارک‌های فضایی که باالقوه تهدیدی برای حیات بر روی کره زمین محسوب می‌شوند، در تحقیقات علمی اخیر به طور فعالی پیگیری شده است. برای انجام مأموریت مشروحه، تاکنون روش‌های متعددی پیشنهاد شده‌اند که در این بین استفاده از کشنده گرانشی شاخص است و از این رو در مقالة حاضر از این روش بهره گرفته شده است. فناوری پرواز آرایشمند فضاپیماها تابع معادلات دینامک نسبی است که برای کنترل فعال آن نیز روش‌های گوناگونی به کار گرفته شده‌اند. در این مقاله از کنترل‌کننده PID که کنترلری با کاربرد گسترده در صنایع گوناگون است و ذاتاً دارای خواص مقاوم بودن نیز هست، به عنوان کنترل‌کننده پایه بهره گرفته شده است و نیز برای بهبود تنظیم ضرایب آن از کنترل فازی استفاده شده که نتایج حاصله از شبیه‌سازی، بیانگر بهبود عملکرد کنترل‌کننده ترکیبی به طرزی مؤثر است.

چکیده [English]

In this paper, the hybrid control of the formation flying of spacecrafts has been investigated. The trajectory deflection of space asteroids, which are potentially life-threatening on Earth, are being actively pursued in recent scientific researches. To accomplish this mission, several methods have been proposed to date, in which case the use of gravity tractor is an indicator and hence the method is used in this paper. The formation flight of spacecrafts technology is a function of the relative dynamic equations, which are also used for its active control. In this way, the PID controller, which is widely used in various industries and inherently has robust properties, has been used as a base controller, and the fuzzy control has been used to improve its adjustment, which results in the results obtained. From simulation, the performance of the combined controller performance is effective.
