Optimizing speed and angle control of stepping motor by using field oriented control
In the present study, field oriented control of step motor implementation has been analyzed sothat it can make a Sensorless control. Efficiency and Facilities of step motor is more than othertypes of electromotor. Therefore, the numbers of mechanisms and different types of turning canbe made into them. Also controlling these motors is easier than other available motors. Steppingmotor has been designed with oriented control in MATLAB software by using a Simulink toolbox. In two methods above, current, torque and engine speed have been investigated by andwithout using Kalman filter. The results showed that using field oriented control can eradicateresonance abnormalities. By using field oriented control, the maximum theoretical engineperformance can be achieved.

Designing Fuzzy Controller for Air Conditioning Systems in order to Save Energy Consumption and Provide Optimal Conditions in Closed Environments (Indoors)
Today air conditioning systems have been considered by all people as one of welfarerequirements in buildings and closed environments. Since a considerable part of energy lossoccurs in ordinary modern systems, new strategies and solutions are developed in the field inorder to save amount of energy consumption and observe environmental considerations. Fuzzycontrol is one of these methods which provide a basic powerful rule for decisions made toguarantee optimal use of cooling and heating system. Hence in this research project datameasured by environment humidity and temperature were used as input variables and fan speedcontroller, humidifier, heaters, and compressors were used as output variables to regulate air flowrate and create humidity, cooling and heating conditions in the environment using fuzzy logic forsystem control.

The compression of MPPT methods in small sized wind power plants
In this paper the maximum power point tracking (MPPT) algorithms for wind energy systems arereviewed. As the amounts of power produced in wind power plants is changing due to theinstantaneous changing nature of the wind, it is desirable to determine the one optimal generatorspeed that ensures maximum energy yield. Thus, it is important to include a controller that cantrack the maximum peak regardless of wind speed. Categorizing the MPPT algorithms can bedone regarding whether it has used sensors or not, as well as according to the techniques used tolocate the peak value. The performance of different MPPT algorithms is compared on the basis ofability to achieve the maximum energy yield and various speed responses. According to availablesimulation results in the literature, in cases through which the flexibility and simplicity inimplementations is considered, the perturbation and observation (P&O) method is preferred, butdifficulties in determining the optimum step-size are the restrictions of this method. Due to itssimplicity, the best MPPT method for wind energy systems has found to be the optimal torquecontrol (OTC).

Velocity Control of Electro Hydraulic Servo System by using a Feedback Error Learning Method
In this paper, a new control method based on FEL electro hydraulic servo control withnonlinear flux and internal friction, has been presented. The new approach based oncontrollers combined by a classic PD controller and a fuzzy controller is smart. This newtechnique has a good ability to control the performance and stability. Simulations have beencarried out in Matlab environment and the results are presented below.

Novel Circularly Polarized Substrate Integrated Waveguide Slot Antenna By Using A Polarizer Technique
circularly-polarized antenna is built based on new SIW(substrate integrated waveguide)structure which contains cavity-backed resonator and a conventional polarized ring with twosquare slits in inner and outer ring that differ 90° at position and is proposed for right-handedcircular polarization (RHCP) and fabricated in two separate layers. A broadband impedancebandwidth of 13.9% and a RHCP axial ratio of 0.5GHz have been obtained under thecondition of less than VSWR ≤2 and axial ratio≤ 3 dB, respectively.

Economic possibility assessment of creating wind power stations at Soltanieh zone of Zanjan province
Due to increasingly expansion of energy consumption and also decreasing and tendency towardsending fossil energy reserves, the current energy cycle needs to use alternative energy speciallywind energy, because it’s considerably cheaper than other recycling sources. The present researchinvestigates possibility of creating wind Power Station economically at Soltanieh zone of Zanajnprovince regarding economical perspectives. Cost of investment and other costs and alsoenvironmental effects, were assessed economically by considering annual obtained energy rate.Several scenarios were investigated; complete price of energy in every kW per hour at eachscenario was calculated and compared with other sources of electricity energy generationespecially fossil power stations. By considering obtained results, it’s expected that creating windpower station at Soltanieh zone has yielded economical benefits.
