This paper proposes a new approach to control a Shunt active filter (SAF) to eliminate harmonic currents and compensate reactive power , this approach called Predictive Direct Power Control (P-DPC) where the Direct Power Control is combined with a Predictive Control , PDC controls active and reactive power to get an unity power factor and when it combined with Predictive Control , the controller can predict future behavior for all possible voltage vectors , and the best vector is chosen for the next sample by minimizing a cost function . we connect this filter with a nonlinear load to the grid and simulate this systemusing Matlab , Simulink and Simpower , the results shows that P-DPC decrease Total Harmonic Distortion (THD%) of line current and make it sinusoidal and improve the power factor .

This paper treats the issue of wind energy storage, mechanically, using the flywheel device. We control the speed of the wind turbine and the flywheel by means of traditional PID controllers. These controllers are designed depending on the system m odel and its parameters. Speed control is achieved by electromagnetic rotor flux orientation as called vector control. Speed reference value of the wind turbine will be generated in order to track the maximum power point. The flywheel reference speed is generated based on a second order filter of power which is considered as a new contribution in this field of research. Frequency converters are not modeled but we only consider the control strategy. The results of modeling and simulation in Matlab satisfy the power smoothing issue and reflect the importance of this study.
This paper presents a three phase shunt Active Power Filter (APF) for power quality improvements in terms of harmonics compensation. The compensation process is based on measure non-liner load currents and Active Filter currents, and then extract t he references from measured currents. Measured currents are then transferred from abc frame to d-q reference frame. A Synchronous Proportional Integral controller (Synchronous PI controller) is used. The control signals then drive the Pulse Width Modulation (PWM) routine, where its output controls the Voltage Source Inverter (VSI) switching devices. The performance of the Active Filter and the Synchronous PI controller is validated though the simulink results in MATLAB environment.
This article examines the possibility of assigning the mobility characteristics of the modifications carried out on the dynamic algorithm to the static algorithm. Furthermore we used NS-2 simulator to evaluate our proposal and to compare it with t he performance of the standard algorithms. The results show the superiority of the modified algorithms over the standard algorithms, especially with network congestion.
Quality Control procedure Of Gamma Spectrometry measurements using semi conductor HPGe Detectors and determination the uncertainty budget of the measurements and calibrations have been prepared. Depending on this procedure we can evaluate the qual ity of the results to be accepted or not, and where the correction actions should be used.
Control charts have been applied in this research, as a measure of Statistical Quality Control (SQC), to control the quality of cotton-polyester blended yarns produced at Al-Wleed Spinning Company. This method is not currently applied at the compa ny, and it is used in this research to check whether or not the production process is statistically in control, and whether or not the variations in quality characteristics are random and cannot be controlled or assignable and can be dealt with.
