The theoretical section presents the principle of operation of an on-site control circuit using a DC motor, as the continuous motor is the main element that rotates at certain angle and thus moves the action to the gearbox which reduces the engine's rotational speed to control the variable resistance which adjusts the voltage Vb to be equal to the voltage Vr The Practical section displays the results.

This research aims to study the effect of rotation speed and armature current density or load current of micro dc motors on the commutation current, especially on the final phase where electrical spark occurs on the motor collector. A relationship of how electrical spark time and density or energy is related to rotation speed and armature current density, will be deduced. This research was supported by special laboratory experiments, and ended up with useful scientific results.
The consumption of power in the industrial field almost reaches approximately 40% of the total generated power. One kind of useless consumption of power is the losses in the electrical motors starting. The impact of the losing power might be ignore d in the continuous and short time working systems. However, in case of periodic starting up, the losing ratio will be exaggerated. Also, the controlling of starting up process will be considerable and can keep the losses at lowest levels. In this paper, the effect of using the Semi-conductors controlling system in DC motors on power losses was studied and compared with control system using resistors starting in periodic short time systems. The obtained results show that there is a relationship between the power saving in KWh per year as a function of the rated motor power and the number of starting up per Hour. Due to conveying from conventional controlling system to modern control system uses semiconductor rectifier.
A lot of researches studies robot arms and the ability of controlling it to track targets which depends on the type of motors used, DC motors or servo motors. In addition to response time that DC and motor can give as a physical structure. Robots consists of number of junctions built of solid materials (robot arms( connected together by motors and the total structure lets the robot to move, these robots can be used in places that humans cannot act inside it or in places which we need a lot of repeated actions. This search aimes to study the robot arm movement by controlling the motors and its response to a drawn line using a PID controller to achive the most accuracy by using the distrubushion constants of the camera lens which used by the robot to see. All the cameras need to be calibrated and the constants used to move the robot in X,Y,Z.
This research deals with improving the efficiency of solar photovoltaic (PV) power systems using a Maximum Power Point Tracker controller (MPPT controller), based in his work on the Maximum Power Point Tracking techniques via the direct control met hod. Which used to control the duty cycle of DC-DC Voltage Converter, to achieve the photovoltaic system works at a Maximum Power Point under different atmospheric changes of the solar insolation and ambient temperature. In this context, our work is focused on the simulation of the components of the power generating system, such as the photovoltaic system, DC-DC Boost Converter and a MPPT controller in Matlab/Simulink environment. The simulating of the MPPT controller was based on several algorithms such as: Constant Voltage algorithm, Perturb and Observe algorithm and Incremental Conductance algorithm by using Embedded MATLAB function. The simulation results showed the effectiveness of the MPPT controller to increase the photovoltaic system power compared with non-use of a MPPT controller. The results also showed the best performance of MPPT controller based on Perturb and Observe and Incremental Conductance algorithm, compared with constant voltage algorithm in tracking the Maximum Power Point under atmospheric changes.
Novel rejected and passed band devices are obtained using techniques in two dimensional Photonic Band Gap microstrip structures. The microstrip is engraved in a PBG dielectric constituted of a via holes array and enclosed in a metallic box. The b oundary element method (BEM) and the fast wave concept iterative process (FWCIP) are combined to evaluate the characteristic of this structure.
