In this study, collective flight, mission execution and decision-making algorithm for airdrop micro munitions with two different swarm algorithm alternatives are examined. Through a concept munition design is created and an aerodynamic database is prepared with the Missile-Datcom software. Six degrees of freedom flight mechanics model, subsystems of munition and environment are modeled. A linear model is obtained and controller is designed. Pole placement method is used in the controller design. Full state feedback assumption may not suitable for the actual problem. For this reason, the autopilot gains of the designed controller are converted into gain values suitable for measurements by using the projection control method. The designed autopilot tracks the commands of the swarm and proportional navigation guidance. The swarm algorithms coefficients are optimized for the nominal state by particle swarm optimization. Alternative algorithms obtained as a result of optimization are tested under various distortions by Monte Carlo analysis. Sensitivity analysis and performance evaluation are examined as well.

Design of Circling Around a Target Controllers for Mobile Robots by Feedback Linearization ŞAMİLOĞLU, ANDAÇ TÖRE; GAZİ, VEYSEL; Koku, Ahmet Buğra (2010-08-28) Unlike the studies in the literature utilizing pre-generated paths for tracking circular trajectories by mobile robots, in this study the circling around a target problem is considered as a periodic system problem and the states in the system kinematics are forced to converge to periodical trajectories. We propose controllers for the circling around a target behavior of mobile robots developed by static and dynamic feedback linearization techniques. We derive the conditions on the underdamped and overdamped...
A Survey on Tactical Control Algorithms for Path Tracking Unmanned Surface Vehicles Kumru, Murat; Leblebicioğlu, Mehmet Kemal (2016-11-15) In this study, a survey on control allocation algorithms in tactical level control for path tracking unmanned surface vehicles (USV) is conducted. The strategic goal in the path tracking problem is to assist navigation solution of an unmanned underwater vehicle (UUV). USV with the help of its onboard acoustic sensors, tracks UUV according to constant bearing guidance rule. The survey on tactical controllers comprises comparisons of tracking performances of USVs under proportional-integral-derivative, pole p...
Estimation of Noise Model Parameters for Images Taken by a Full-frame Hyperspectral Camera DEMİRKESEN, Can; Leloğlu, Uğur Murat (2015-09-23) Noise has to be taken into account in the algorithms of classification, target detection and anomaly detection. Recent studies indicate that noise estimation is also crucial in subspace identification of Hyper Spectral Images (his). Several techniques were proposed for noise estimation including: multiple linear regression based techniques, spectral unmixing and remixing etc. The noise in HSI is widely accepted to be a spatially stationary random process. But the variance of the noise varies from one wavele...
Evaluation of the site amplification factors estimated by equivalent linear site response analysis using time series and random vibration theory based approaches Stanko, Davor; Gülerce, Zeynep; Markusic, Snjeana; Salic, Radmila (2019-02-01) The objective of this study is to estimate and compare the site amplification factors (AFs) using two different one dimensional (1-D) equivalent-linear (EQL) site response analysis approaches: the time series (TS) approach and the random vibration theory (RVT) based method. For this purpose, random soil profiles combined with different soil types, EQL soil properties, and unit weights are tested at several input ground motion levels. Analysis results showed that the AFs estimated by the TS-approach are syst...
Optimization of physical parameters of an underactuated quadrupedal robot Karagoz, Osman Kaan; Ankaralı, Mustafa Mert (2018-01-01) In this paper, we present the comparison of different optimization algorithms that are used to optimize the parameters of a simulated legged robotic platform. We compare the results obtained by applying different algorithms on the same model and show the relative advantages and disadvantages of these algorithms. The tested algorithms are Particle Swarm Optimization, Binary Coded Genetic Algorithm, Broyden-Fletcher-Goldfrab-Shannon Algorithm and Method of Zoutendijk. We showed that the globally optimal param...
