The purpose of this research is to design and realization of an electronic circuitthat is able to control the water level in a tank. The circuit shows a tank water level in decimal numbers and controls the volume of water in the tank. So that when th e level of water drops below a specific value that is preselected using a probe, the pump water works. When the water level reaches to another limit value, the pump stops working.We used for water level control a container which is made by transparent glass with volume of 15 L. the container is divided in nine levels. In addition to this purpose, because of large applications for realized electronic board, The circuit measures the speed of rotation of DC motorsin a wide range (0001 to 9999) cycles during a chosen period of time that ranges from 1 sec to 110 sec and display the speed of rotation in decimal numbers that appears on four displays. Moreover, the circuit contains a switch reset/start, for display clear and restart of measurement. This study was carried out on samples of tap water, for several values of distance between the probes, and power supply. We found a quick response in showing levels and high efficiency in performance. We measured the number of special motor cycles for several values of the power supply during 30 s and 60 s, and the relation between the number of cycles and applied voltagewas drawingwe found it a linear relation.
محرك الخطوة من أكثر المحركات المستخدمة في أنظمة التحكم عندما يراد التحكم بالحركة و الموضع معاً، و لعل المحرك الخطوي الهجين يعتبر من أهم هذه الأنواع ، و موضوع أنظمة التحكم الخاصة بعمل هذا النوع من المحركات يعتبر مهماً جداً خاصة مع استخدام مفهوم الأ تمتة في هذه الأيام، لذا فإن تصميم نموذجٍ لنظام التحكم و محاكاته باستخدام برنامج MATLAB يعد تطبيقاً عملياً لنظام التحكم بعمل المحرك الخطوي الهجين، و دراسة العوامل المؤثرة عليه ببساطة و سهولة و بتوفير للوقت و الجهد و الكلفة إضافة لإمكانية التأكد من صحة النتائج و دقتها.
In this paper, an adaption mechanism for control signal weighting factor in Generalized Predictive Control (GPC) Technique has been build. This factor changes according to the amplitude of the measured disturbance affecting the acid influent in pH Neutralization process. The main purpose of this adaption is to reduce rigorousness and severity of the manipulated variable of alkaline flow actuator, which result in protecting the actuator from damage, so lengthen its life and shrinking the maintenance costs. The efficiency of the Adaption was observed by calculating the integral of the absolute value of the error (IAE) and the integral of absolute derivative signal (IADS) from simulation results.
In this paper, we presents a solution for those problems by using (CAN) protocol in ATM networks due to many features such as the priority of access and lose-free bus arbitration. We designed a new application layer for using (CAN) in ATM network. Then we compared this proposal pattern with the current ATM network by using MATLAB.
The actual effect of unplanned transition of rural environment with its different components towards urban areas had played a big role in giving the gray tincture on the housing reality of Syrian cities in general, which in turn released a problem that faced planners to solve as one of the most important priorities through concentrating on the possibility of selective elevating of positive specifications of the rural environment as a large effect contributing factor in solving the housing problem through suggesting a group of helping solutions by implementing them as a developing type with a rural quality in actual stopping of housing problem.
