A PID controller satellite attitude yaw-axis control system was designed to step the angle of the satellite body via actuating a precise angular position of a DC motor as quickly and accurately as most optimally possible. The (PID) controller was advantageously chosen for its quick transient response and zero steady-state error. A mathematical model has been derived for the whole satellite attitude yaw-axis control
system. Then, the computation power of the MATLAB is utilized to obtain a generalized optimal controller design that enables the satellite attitude yaw-axis control system to have the quickest settling time without excessive overshoot and zero steady state error.

لما كانت القواعد الدستورية التي تقرر ان السيادة للشعب وهو مصدر السلطات, تقتضي بوجوب التفرقة بين السيادة التي ينفرد بها لشعب وبين ممارسة السيادة من قبل الحكام حيث يتعين ان تمارس في اطار الحدود المقررة بالدستور والقانون, والا فالمسألة هي الجزاء على من لا يلتزم.
