Previous work1 has shown a significant potential for improving the accuracy of direct fire spinning projectiles through the implementation of aerodynamic control. A guidance law optimized for this application was developed. Further research has shown that the guidance law cannot adjust quickly enough to accommodate actuator nonlinearities and uncertainties. Of particular interest is the use of miniature synthetic jets, which achieve a control force by interacting with the flow. The full model of such actuators might not be completely known leading to decreased controlled system performance. Actuator induced moment effect causes amplification or attenuation of the control force depending on the moment direction causing increased target misses and peak control force. Wind disturbances are expected to cause further performance degradation. We describe and provide a preliminary evaluation of a method of dealing with these problems by augmenting the guidance law with an adaptive controller.

A Model based approach for aircraft sensor fault detection
Serçekman, Ömür; Kutay, Ali Türker; Department of Aerospace Engineering (2018)
This thesis presents a reformative approach to a model-based fault detection and diagnosis (FDD) method that improves the capability of aircraft flight control systems and acquires low complexity and computational requirements. The main objective of the FDD techniques that are extensively applied in industrial systems is to increase the sensitivity of fault detection scheme with respect to additional noise, uncertainty or disturbances. The designed fault detection model is integrated to a civil aircraft mod...
An effectiveness evaluation method for airburst projectiles
Saygın, Oktay; Kocaoğlan, Erol; Department of Electrical and Electronics Engineering (2011)
Airburst projectiles increase the effectiveness of air defense, by forming clouds of small pellets. In this work, in order to evaluate the effectiveness of airburst projectiles, Single Shot Kill Probability (SSKP) is computed at different burst distances by using three lethality functions defined from different measures of effectiveness. These different measures are target coverage, number of sub-projectile hits on the target and kinetic energy of sub-projectiles after burst. Computations are carried out fo...
A closed-loop flight control experiment using active flow control actuators
Kutay, Ali Türker; Muse, Jonathan A.; Brzozowski, Daniel P.; Glezer, Ari; Calise, Anthony J. (2007-07-02)
Closed-loop pitch control on a moving 1-DOF wing model is investigated in wind tunnel experiments. The model's attitude is controlled over a broad range of angles of attack when the baseline flow is fully attached using bi-directional pitching moment that is effected by flow-controlled trapped vorticity concentrations on the pressure and suction surfaces near the trailing edge. In the present work, the model is trimmed using a position feedback loop and a servomotor actuator. Once the model is trimmed, the ...
A Test Setup for Evaluating Long-term Measurement Characteristics of Optical Mouse Sensors
Kanburoglu, Furkan A; Dölen, Melik; Koku, Ahmet Buğra (2007-06-01)
Due to significant advancements in optical navigation technology, optical mouse sensors (OMS) are increasingly employed as low-cost motion sensora in personal computing and robot navigation. This paper proposes a new test bed to study the long-term measurement characteristics of emerging OMS devices. With the utilization of this set-up, the attributes of a high-resolution OMS (Agilent ADNS-2051) are investigated under various critical operating conditions like changing surface velocity and the pattern. The ...
A Knowledge based approach in GMTI for the estimation of the clutter covariance matrix in space time adaptive processing
Anadol, Erman; Tanık, Yalçın; Department of Electrical and Electronics Engineering (2012)
Ground Moving Target Indication (GMTI) operation relies on clutter suppression techniques for the detection of slow moving ground targets in the presence of strong radar returns from the ground. Space Time Adaptive Processing (STAP) techniques provide a means to achieve this goal by adaptively forming the clutter suppression filter, whose parameters are obtained using an estimated covariance matrix of the clutter data. Therefore, the performance of the GMTI operation is directly a ected by the performance o...
