An approximate optimal indirect regulation problem is considered for two nonlinear uncertain agents. influencing agent tasked with optimally intercepting and directing a roaming to goal location. The not directly controlled by the agent, but instead moves based on some interaction dynamic. To overcome this challenge, virtual controller designed yield desired influence agent. In addition, an dyn...

در میان شبکۀ معابر شهری، راه‌های اضطراری امدادرسانی حین زلزله، به‌ویژه مرحلۀ پاسخ به بحران، نقش مهمی ایفا می‌کنند. حفظ عملکرد این شبکه از معابر، ساعات اولیۀ پس اهمیت بسزایی دارد. محافظت و مقاوم‌سازی اجزای آسیب‌پذیر شبکه، به‌خصوص پل‌ها، پیش وقوع تأثیر شایان توجهی کاهش خسارات آسیب‌ها اغلب اوقات تمامی آسیب‌پذیر، به‌دلیل محدودیت بودجه، عملاً ناممکن است. ایجاب می‌کند که با شناسایی دقیق گزینه‌های ابتد...

This paper addresses the adaptive inverse optimal output regulation problem for a class of uncertain nonlinear systems driven by an exosystem. The unknown parameters, internal disturbances, and unmeasured states are contained in system. Firstly, is decomposed into feedforward control design which can be solved model based on theory, stabilization problem. Then auxiliary system designed, new sta...

This study presents a control design of roll motion for vertical take-off and landing unmanned air vehicle (VTOL-UAV) based on the Model Reference Adaptive Control (MRAC) scheme in hovering flight phase. The adaptive laws are developed UAV system under nonparametric uncertainty (gust wind disturbance). Lyapunov-based stability analysis controlled has been conducted have accordingly developed. U...

This letter proposes an adaptive neural network-based backstepping controller that uses rigid graph theory to address the distance-based formation control problem and target tracking for nonlinear multi-agent systems with bounded time-delay disturbance. The radial basis function network (RBFNN) is used overcome compensate unknown nonlinearity disturbance in system dynamics. effect of state agen...

This paper addresses three related issues concerning the path following control of a podded propulsion unmanned surface vehicle (USV), namely modeling, guidance and control. The pod is different from the general propeller-rudder propulsion device, and its essence is a vector thruster. Therefore, first, through various assumptions and simplification, the three-degree of freedom (DOFs) planar mot...

This paper presents an adaptive Takgi-Sugeno (T-S) fuzzy terminal sliding-function controller (AFTSFC) approach to synchronize two chaotic systems with parameter mismatch. First, an appropriate terminal sliding function (TSF) is designed and then represented by the T-S fuzzy model. The T-S fuzzy terminal sliding-function (FTSF) is applied to the control law. Different from classical terminal sl...

Compared with most existing results concerning unmanned aerial vehicles (UAVs) wherein two-degree or only attitude/longitudinal dynamics are considered, this paper proposes an event-based fault-tolerant coordinated control (FTC) for multiple fixed-wing UAVs such that the consensus tracking of velocity and attitude is achieved in presence actuator faults, external disturbances modeling uncertain...
