چکیده
در این مقاله، قانون کنترلی مقاوم برای دینامیک طولی غیرخطی موشک براساس تئوری لیاپانوف و کنترل مدلغزشی برای ردیابی
زاویه حمله ارائه شده است. فرض بر این است که در معادلات غیرخطی، نامعینی غیرتطبیقی وجود دارد. در روش پیشنهادی، بهره های کنترل کننده توسط الگوریتم اجتماع ذرات بهینه شده است. برای این منظور تابع هزینه ای با استفاده از خطای ردیابی خروجی تعریف شده است. نتایج شبیه سازی برتری عملکرد کنترل کننده پیشنهادی را نسبت به کنترل کننده معمول PID در حضور نامعینی غیرتطبیقی نشان می دهد.

چکیده [English]
In this paper, a robust control law is proposed, based on Lyapunov’s theory and sliding mode control theory, in
order to track the angle of attack in nonlinear longitudinal dynamics of a missile. It is assumed that there are unmatched
uncertainties in the nonlinear systems. In the proposed algorithm, the controller gains are optimized by Particle Swarm
Optimization (PSO) algorithm. For this purpose, a cost function is extracted from the output tracking error. Simulation results
show that the proposed algorithm has better performance than conventional Proportional-Integral-Derivative (PID) controller in
the presence of unmatched uncertainties.
