© 2021 Chinese Society of Aeronautics and AstronauticsA new three-dimensional missile guidance law to control the impact vector against a stationary target is proposed. The composite guidance law has two well-known components: Apollo descent guidance and trajectory shaping guidance. These respectively linear and planar guidance laws are combined to achieve a specified impact direction. The main idea is to define an impact plane and to steer the missile onto this plane using Apollo descent guidance while concurrently performing trajectory shaping with reference to the impact plane. The resulting guidance law is expressed by a single equation in vector form, which is straightforward to implement. Because it originates from an optimal formulation, the performance of the proposed technique is expected to be satisfactory. This is confirmed by comparative simulation runs, which also involve the method known as generalized explicit guidance.

Missile autopilot design by projective control theory Doruk, Reşat Özgür; Kocaoğlan, Erol; Department of Electrical and Electronics Engineering (2003) In this thesis, autopilots are developed for missiles with moderate dynamics and stationary targets. The aim is to use the designs in real applications. Since the real missile model is nonlinear, a linearization process is required to get use of systematic linear controller design techniques. In the scope of this thesis, the linear quadratic full state feedback approach is applied for developing missile autopilots. However, the limitations of measurement systems on the missiles restrict the availability of ...
Cooperative Guidance Law for High-Speed and High-Maneuverability Air Targets Cevher, Firat Yilmaz; Leblebicioğlu, Mehmet Kemal (2023-2-01) In this paper, a novel cooperative and predictive guidance law is proposed to intercept high-speed and high-maneuverability targets with inferior interceptors. The purpose of guidance is cooperatively covering the most-probable locations where the target may be in the future. To fulfill this purpose, predicted target states in the form of a probability density function were obtained using limited target information, i.e., noisy position data for one case and maneuverability limits for the second case, at fi...
Static aeroelastic modeling and parametric study of stacking sequence for laminated composite missile fins Aslan, Göktuğ Murat; Kurtuluş, Dilek Funda; Department of Aerospace Engineering (2018) In this thesis, a surface-to-surface missile model with laminated composite fins is examined with respect to one-way static aeroelastic response under constant supersonic flight conditions. Two different modified double wedge fins or control surfaces using for control actuation system of a missile are investigated and compared in terms of aerodynamic and linear structural characteristics in order to minimize tip deflection. A serial set of steady-state supersonic Computational Fluid Dynamics (CFD) analyses ...
Nonlinear Guidance of Aircraft Formations Tekinalp, Ozan (null; 2015-01-05) Nonlinear formation flight control algorithm for a pair of unmanned aerial vehicles (UAV) is proposed. The leader-follower approach to formation flight is adopted. The leader maintains a prescribed trajectory while the follower is controlled to track and maintain a fixed relative distance from its leader. Two nonlinear guidance algorithms, Lyapunov and State Dependent Ricatti Equation, (SDRE) based are proposed for the relative guidance of the follower UAV. The resulting formation control systems are tested...
End-to-end networks for detection and tracking of micro unmanned aerial vehicles Aker, Cemal; Kalkan, Sinan; Department of Computer Engineering (2018) As the number of micro unmanned aerial vehicles (mUAV) increases, several threats arise. Hence, there is a need for a system that can detect and track them. In this thesis, an object detection model based on convolutional neural networks for mUAV detection, and a novel end-to-end object tracking architecture are proposed. To solve the scarce data problem for training the detection network, an algorithm for creating an extensive artificial dataset by combining background-subtracted real images is proposed. I...
