چکیده
در این پژوهش به طراحی و شبیه‌سازی کنترل کننده ترکیبی مودلغزشی پیوسته مرتبه بالای تطبیقی همراه با شبکه عصبی برای یک موشک زمین به هوا به منظور کمینه کردن زمان پرواز موشک تا هدف پرداخته شده است. مدل‌سازی موشک و هدف در این مقاله بصورت دو بعدی در نظر گرفته می‌شود و بهبود کنترل کننده‌ها جهت کمینه شدن فاصله برخورد تا هدف و زمان پرواز ایجاد شده ‌‌است. نوآوری این مقاله طراحی کنترل کننده ترکیبی مودلغزشی پیوسته مرتبه بالای تطبیقی با تلفیق شبکه عصبی در مدل هدایت و کنترل یکپارچه است. ابتدا کنترل کننده مودلغزشی متداول طراحی می‌شود، سپس به طراحی کنترل کننده مودلغزشی پیوسته مرتبه بالای تطبیقی پرداخته می‌شود. در ادامه با افزودن شبکه عصبی، عملکرد کنترل کننده پیشنهاد شده بهبود می‌یابد. باتوجه به نتایج شبیه‌سازی‌ها می‌توان نشان داد که استفاده از کنترل کننده پیشنهادی و به‌کارگیری مدل هدایت و کنترل یکپارچه، زمان برخورد باهدف به مقدار 87 درصد، نسبت به کنترل کننده مودلغزشی متداول کاهش یافته است.

چکیده English

This study focuses on the design and simulation of an adaptive higher-order continuous sliding mode hybrid controller, enhanced with a neural network, for surface-to-air missile systems. The objective is to reduce both the flight time and miss distance in two-dimensional interception scenarios. A baseline sliding mode controller is initially developed, followed by the implementation of a higher-order adaptive continuous variant. The proposed hybrid controller integrates a neural network within the guidance and control loop to dynamically compensate for modeling uncertainties and improve tracking precision. Simulation results confirm that the integrated approach significantly enhances system responsiveness and target acquisition accuracy. Compared to the conventional sliding mode controller, the hybrid method achieves an 87% reduction in time-to-hit, demonstrating substantial improvement in interception performance.
