The re-use of return air in central conditioning systems is one of the most important
procedures for saving power consumption. However, the requested fresh air of the people
existed within the conditioning space imposes determining the number of ti
mes to be used.
This research aims to link the work of the central conditioning system (heating) of a
facility with the number of people existing within this facility by modifying the ratio of
mixed fresh air and return air to save the electrical power consumption. Also, to raise the
temperature of the mixture air by controlling the flow of hot water continuously rather than
using on-off technique. As well as, to respond to any change in the number of people and
get rid of repeated machine starting.
Our research has been done by using specialized physical model consisted of test
room, heat and movement sensors, pump, water tank, heat exchanger and air mixing
blades. These devices are controlled by microcontroller type PIC16F877A.
The experimentally obtained results showed the ability of controlling the amount of
return air depending on the number of people and controlling the speed of the pump
continuously providing a saving of electrical energy consumption up to 68% compared
with the case of full speed.
This paper presents a robust cerebellar model articulation
controller (CMAC) for quadcopter system.
We simulate this systems by using Matlab and Simulink, and we
find that this control guarantees good balance performance and
acceptable robust per
formance. And we compare our CMAC with
other systems using CMAC but in structures differ of our CMAC
structure.
يقوم هذا المشروع على تطبيق طرق التحكم المتقدم التي تمت دراستها في تخصص هندسة الميكاترونكس وأهمها (state feedback via pole placement) على نظام ميكاترونكس متكامل ذو ثلاث درجات حرية, يتكون من عربة معلق بها بندول, تتحرك هذه العربة على ذراع متأرجح, وثلاثة
مجسات لقياس موقع العربة وزاوية تأرجح الذراع وزاوية تأرجح البندول, و (Servo motor) يقوم بأرجحة الذراع لضبط حركة العربة
