Controlling of A Rod Angle Using A Fan

Abstract

As an application of the mechatronics systems this project had suggested , the main objective of this project is scientific one , it is a direct application on mechatronics systems, since it has a control items or controllers, motions , accuracy and feedback. The project is one degree of freedom, so one fan is needed here. The project has tow main parts , mechanical part and electrical ( and digital) part, the mechanical one has a vertical – oriented fan placed on one end of a bar, this bar jointed at the middle by a hinge with a cylindrical column, the cylindrical column fixed at the bottom with a base. The electrical ( and digital) part has a keypad to input the command, a fan motor,LCD , microcontroller, the wirings and the position detector with feedback to get an accurate position. This project is concerning to control the angle of the middle-joint rod when rotating about the hinge by interring the intended angle on the potentiometer, this command is transmitted to electrical current, this current drives the fan motor and the fan rotates with speed according to the angle, the feedback signal decides that it’s the wanted angle.
