ملخص المقالة :
در اين مقاله يک کنترل‌کننده به روش جدولبندي بهره فازي براي کانال‌هاي هدايتي موشک‌هاي تاکتيکي طراحي گرديده است به نحوي که در کليه شرايط پروازي پاسخ مناسبي داشته باشد. ديدگاه اين طراحي تعيين مراکز نواحي جدولبندي بهره فازي با آموزش يک سيستم فازي بر اساس اطلاعات فشار ديناميکي و سرعت موشک و ضرايب مدل خطي سيستم در سراسر نقاط کاري آن مي‌باشد. آموزش سيستم فازي با استفاده از يک روش مبتني بر ترکيب حداقل مربعات خطي و الگوريتم ژنتيک انجام مي‌شود تا هم رسيدن به بهينه کلي ميسر شود و هم سرعت همگرايي خوبي حاصل شود. به علاوه در سيستم فازي استفاده‌شده، توابع عضويت با خصوصيات مناسبي به کار گرفته مي‌شوند تا طراحي ساده‌تر و مؤثرتر انجام گيرد. کارآيي اين روش با نتايج شبيه‌سازي نشان داده مي‌شود.
