Aerodynamic characteristics of missiles depend strongly on wind angles, that is, angle of attack and sideslip angle. However it is impractical to measure these angles during missile testing. Therefore, without direct information of the wind angles, it becomes a difficult problem to be able to accurately estimate the missile aerodynamic parameters from flight tests. This thesis addresses this problem and suggests an approach to estimate missile aerodynamic parameters successfully without wind angles measurements. Instead of reconstructing wind angles with post-process calculations prior to estimation, reconstruction process is handled within the estimation. The algorithm developed is tested with simulated missile data. Results are compared with true values used in simulation. It is demonstrated that suggested approach can provide accurate and reliable estimations without wind angles measurements. The approach is also applied to real flight test data of a missile with success.

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 ...
Sliding mode guidance of an air-to-air missile
Ulu, Muharrem; Leblebicioğlu, Mehmet Kemal; Department of Electrical and Electronics Engineering (2013)
Pursuit of a highly maneuverable aircraft by an air-to-air missile requires a solution to a challenging guidance and control problem. Precision is the most important need for these missiles. Appropriate guidance commands that are generated by the guidance method and an autopilot that can fulfil the agility needs of such a missile are the keys of minimizing the distance between the missile and the target and a successful interception. In this thesis, autopilot and guidance method design of an air-to-air miss...
Fuzzy logic guidance system design for guided missiles
Vural, A. Özgür; Özgören, Mustafa Kemal; Merttopçuoğlu, Osman; Department of Mechanical Engineering (2003)
This thesis involves modeling, guidance, control, and flight simulations of a canard controlled guided missile. The autopilot is designed by a pole placement technique. Designed autopilot is used with the guidance systems considered in the thesis. Five different guidance methods are applied in the thesis, one of which is the famous proportional navigation guidance. The other four guidance methods are different fuzzy logic guidance systems designed considering different types of guidance inputs. Simulations ...
Missile guidance with impact angle constraint
Çilek, Barkan; Kutay, Ali Türker; Department of Aerospace Engineering (2014)
Missile flight control systems are the brains of missiles. One key element of a missile FCS is the guidance module. It basically generates the necessary command inputs to the autopilot.Guidance algorithm selection depends on the purpose of the corresponding missile type. In this thesis, missile guidance design problem with impact angle constraint is studied which is the main concern of anti-tank and anti-ship missiles. Different algorithms existing in the literature have been investigated using various anal...
Aeroservoelastic modeling of a missile control
Nalcı, Mehmet Ozan; Kayran, Altan; Department of Aerospace Engineering (2013)
In this thesis, aeroservoelastic modeling of a typical Missile Control Fin was performed. MSC®PATRAN, MSC®NASTRAN, MSC®FlightLoads and Dynamics, MATLAB® and MATLAB®Simulink were used for technical computing, modeling and simulation throughout the study. Linear models of the control fin structure, aerodynamics and servo-actuator system were developed, so as to be able to analyze the aeroservoelastic system in frequency and time domains. The flutter characteristics of the missile control fin for different fli...
