چکیده
در این مقاله، ارزیابی کنترل وضعیت مغناطیسی با استفاده از قوانین کنترلی PD و LQR بررسی شده است. برای ارزیابی این قوانین کنترلی از «شبیه‌ساز سه‌درجۀ آزادی کنترل وضعیت ماهواره مبتنی بر یاتاقان هوایی» استفاده شده است. معادلات دینامیکی و سینماتیکی توسعه‌یافته برای شبیه‌ساز با تست آزمایشگاهی حلقه‌باز صحه‌گذاری می‌شود. پس از اثبات صحت مدل‌سازی، قوانین کنترلی با مقایسۀ نتایج شبیه‌سازی و تست آزمایشگاهی حلقه‌بسته ارزیابی می‌شود. به دلیل محدودیت‌های ذاتی شبیه‌ساز، پیاده‌سازی کنترل‌کنندۀ وضعیت مغناطیسی تنها در راستای یک محور امکان‌پذیر است. نتایج تست‌های آزمایشگاهی نشان‌دهندۀ عملکرد بهتر قانون کنترلی LQR و دقت مناسب آن برای بسیاری از مأموریت‌هاست. بنابراین، با تعمیم کنترل‌کنندۀ LQRشبیه‌سازی سه‌محوره برای یک ماهواره انجام شده است.

چکیده [English]
In this paper, the three-axis magnetic attitude control using PD and LQR control laws have been studied in a lab environment. Evaluation of the magnetic attitude control with this control laws is done by a "three degrees of freedom air-bearing simulator". Developed dynamic and kinematic equations to be used in actual simulator are evaluated by open loop test. Then control laws evaluated by comparing close loop simulation and laboratory test. Due to the inherent simulator limitations, magnetic attitude control only possible in the yaw axis. Laboratory test results indicate the improved and accurate performance of LQR control law for most satellite missions. Therefore by generalized LQR controller, three-axis simulation was performed for a satellite.
