In this work, EPICS (Experimental Physics and Industrial Control System) program chosen for the control system of the Turkish Accelerator Center (TAC) infrared free electron laser (IR-FEL) laboratory has been introduced. By using EPICS program, the control of all sub systems can be provided from SEL production phase to the user stations in IR-FEL laboratories. Beam current and position in a linear electron accelerator (e-linac) system for TAC IR-FEL laboratory have been investigated from source to dump by using EPICS program. [ABSTRACT FROM AUTHOR]

This study includes altitude stabilization, hovering control and attitude control of quadrotor. Classically PD controller derived and applied to this system. Inverse dynamic control, feedback linearization control and sliding mode control methods have used to derive as nonlinear controllers. Linear and nonlinear control techniques applied to mathematical model as simulation and applied to quadrotor platform for experimental results. Derived control methods have been performed using computer simulations and compared the results according to this study objectives. [ABSTRACT FROM AUTHOR]

In this work, a novel and national digital flow modelling capability has been developed as a further developing cluster for FLOWER Digital Modelling. With the developed model, in order to determine fast-variying flight stability borders and developing flight control softwares, related to flight dynamics and aero-dymanics, eddification of the daraught on an air vehicle during fast-varying wing and tail position changes has been estimated on designing body and wing of high manoeuvre-capable fixed-wing air vehicles.

In this study a projectile monitoring and control system for multistage induction coil gun has been designed, and relevant prototype is produced. Synchronization between the projectile coil and stator coil becomes more important, especially, as the number of stages increases. Both the absence of a mechanical or electrical contact between the coils and presence of only magnetic coupling between the projectile and stator coils also render solving the problem of synchronization between these two coils difficult. A new microcontroller monitoring and control system is proposed to minimize timing error for multistage coil guns up to 6000m/s. The control system produced and the related software prepared have been elaborated within the context of this study. [ABSTRACT FROM AUTHOR]

Although automatic flight control systems fairly lighten the pilots' workloads, they may fail as the other systems. In these systems, sensors, actuators and the control surface failures can cause undesirable results to arise. However, it can be possible to tolerate the failures in flight control systems by using what is known in literature as fault tolerant control which makes the operations of systems possible against some types of failures. The fault tolerant control is composed of detection of failures, isolation, and reconfiguration of system stages. Herein, an application is made for the fault detection of a helicopter by observer equipment using lateral movement equations. The application allows user to have an opinion for conditions that can not be directly measured as well as the fault detection based on comprehensive condition estimate. [ABSTRACT FROM AUTHOR]

Maintaining desired flight conditions in flight envelope for a long period is the primary control problem in aircraft flight control. Due to internal and external disturbances, dynamic behaviour of aircraft may change in a short period of time. Thus a control system designed for a flight condition, may not provide the desired stability and performance characteristics in case of deviation from the equilibrium point. There are numerous studies regarding flight control in the literature. Most of the applications about the design of fuzzy flight control are in simulation level. In this study, the design of classical and fuzzy PD controller for the altitude control system is analyzed and the results are compared for a very large four-engine passenger jet aircraft.
