چکیده

در قوانین هدایت مبتنی بر نرخ زاویه خط دید، شتاب جانبی وسیله به گونه‌ای تعیین می‌گردد که نرخ زاویه خط دید (بین جسم و هدف) صفر شود. با ثابت ماندن زاویه خط دید، اگر سرعت جسم از سرعت هدف بزرگ‌تر باشد آنگاه جسم به هدف مورد انتظار به صورت مجانبی خواهد رسید. در این مقاله، به ارائه یک الگوریتم هدایت جدید مبتنی بر زاویه خط دید جهت استفاده در سیستم‌های هدایت دو بعدی پرداخته شده است. بدین منظور، با توجه به روابط حاکم بر موضوع و استفاده از روابط مثلثاتی، قانون هدایت پیشنهادی به یک رابطه جبری منجر می‌گردد. اگر چه رویکرد به کار گرفته شده در این مساله هدایت، مستقل از نرخ زاویه خط دید می‌باشد، اما صفر شدن تغییرات زاویه خط دید با کمک منطق ارائه شده، در لحظه اعمال قانون هدایت رخ خواهد داد. قانون استخراج شده در یک مساله هدایت دو بعدی ارزیابی شده و مزیت راه‌حل پیشنهادی در مقایسه با روش‌های دیگر نشان داده خواهد شد.
