چکیده
280 control on advanced, high-speed flight vehicles. Effective manipulation of a flow field using flow-control technologies can lead to a number of significant benefits to aerospace vehicle systems, including enhanced performance, maneuverability, payload, and range, as well as lowered overall cost. A research team led by APL is investigating the time-dependent fluid dynamic interactions between colocated pulsed jets in order to demonstrate a potentially revolutionary system for high-speed flow control that leverages SparkJet technology (Fig. 1). The plasmadynamic SparkJet actuator generates exhaust streams that can penetrate supersonic as well as subsonic boundary layers. Operated at high frequencies (~1 kHz), the unsteady actuation can be targeted to influence the inherent

Improvement Performances of Active and Reactive Power Control Applied to DFIG for Variable Speed Wind Turbine Using Sliding Mode Control and FOC
This paper deals with the Active and Reactive Power control of double-fed induction generator (DFIG) for variable speed wind turbine. For controlling separately the active and the reactive power generated by a DFIG, field oriented control (FOC) and indirect sliding mode control (ISMC) are presented. These non linear controls are compared on the basis of topology, cost, efficiency. The main cont...
متن کاملSensorless Model Reference Adaptive Control of DFIG by Using High Frequency Signal Injection and Fuzzy Logic Control
In this paper, a new sensorless model reference adaptive method is used for direct control of active and reactive power of the doubly fed induction generator (DFIG). In order to estimate the rotor speed, a high frequency signal injection scheme is implemented. In this study, to improve the accuracy of speed estimation, two methods are suggested. First, the coefficients of proportional-integral ...
متن کاملActive Damping and Vibration Control for Aircraft Fin and Appendage Structures
Numerous vibration control techniques, employing both passive and active methods, have been developed and tested over the last several decades. Some of these techniques are in widespread use, while others have rarely or never left the laboratory. This paper considers the value that vibration damping and control of aircraft fins and appendage structures can have in reducing loads and subsequent ...
