Autopilot and guidance for anti-tank imaging infrared guided missiles

Özcan, Ali Erdem
An anti-tank guided missile is a weapon system primarily designed to hit and destroy armored tanks and other armored vehicles. Developed first-generation command-guided and second-generation semi-automatic command guided missiles had many disadvantages and lower hit rates. For that reason, third generation imaging infrared fire-and-forget missile concept is very popular nowadays. In this thesis, mainly, a mathematical model for a fire-and-forget anti-tank missile is developed and a flight control autopilot design is presented using PID and LQR techniques. For target tracking purposes, “correlation”, “centroid” and “active contour” algorithms are studied and these algorithms are tested over some scenarios for maximizing hit rate. Different target scenarios and countermeasures are discussed in an artificially created virtual environment.


Autopilot and guidance algorithms for infrared guided misiles
Kılıç, Kayhan Çağlar; Ünver, Baki Zafer; Department of Electrical and Electronics Engineering (2006)
Guided missiles are among the most effective threats against air platforms. Aircraft and helicopter losses in the last decades were mostly due to guided missiles, 70% of which were infrared guided missiles. Today, there are as many as 500,000 shoulder-fired missiles in military arsenals around the world, whose guidance algorithms enable them to track the desired trajectories very precisely. In this thesis, main focus is on defining infrared missile guidance and control algorithms in order to study on variou...
Development of a DSP-FPGA-based resolver-to-digital converter for stabilized gun platforms
Zengin, Yasin; Erkmen, İsmet; Department of Electrical and Electronics Engineering (2010)
Resolver, due to its reliability and durability, has been used for the aim of shaft position sensing of military rotary systems such as tank turrets and gun stabilization platforms for decades. Ready-to-use resolver-to-digital converter integrated circuits which convert the resolver signals into position and speed measurements are utilized in servo systems most commonly. However, the ready-to-use integrated circuits increase the dependency of the servo system to hardware components which in turn decrease th...
Modelling and controller design of the gun and turret system for an aircraft
Mert, Ahmet; Leblebicioğlu, Mehmet Kemal; Department of Electrical and Electronics Engineering (2009)
Gun and gun turret systems are the primary units of the weapon systems of an aircraft. They are required to hit targets accurately during operations. That is why a complete, high precision control of weapon systems is required. This function is provided by accurate modeling of the system and the design of a suitable controller. This study presents the modeling of and controller design for the gun and turret system for an aircraft. For the controller design purpose, first the mathematical model of the system...
Feature set evaluation for a generic missile detection system
Avan, K. Selçuk; Tuncer, Temel Engin; Department of Electrical and Electronics Engineering (2007)
Missile Detection System (MDS) is one of the main components of a self-protection system developed against the threat of guided missiles for airborne platforms. The requirements such as time critical operation and high accuracy in classification performance make the ‘Pattern Recognition’ problem of an MDS a hard task. Problem can be defined in two main parts such as ‘Feature Set Evaluation’ (FSE) and ‘Classifier’ designs. The main goal of feature set evaluation is to employ a dimensionality reduction proces...
Autopilot design and guidance control of ulisar uuv (unmanned underwater vehicle)
Isıyel, Kadir; Leblebicioğlu, Mehmet Kemal; Department of Electrical and Electronics Engineering (2007)
Unmanned Underwater Vehicles (UUV) in open-seas are highly nonlinear with system motions. Because of the complex interaction of the body with environment it is difficult to control them efficiently. Linearization is applied to system in order to design controllers developed for linear systems. To overcome the effects of disturbances, a mathematical model which will compensate all disturbances and effects of linearization is required. In this study first a mathematical model is formed wherein the linear and ...
