Abstract

In this modern era technology, an embedded system is widely used in most electric and electronic component for specific task. It is simple systems that are built up for accomplish and control specific task. The main purpose of this project is to design and developed an embedded an embedded control system for controlling a dc motor using a microcontroller. An embedded system consist three important elements during the development. One of the elements is designing a hardware that consist a schematic diagram. Next is the development of the control part. For this project, microcontroller was selected because of the repeated instruction can be used inside the microcontroller. For controlling a dc motor, an element of the control system were added which is PID algorithm. PID algorithm consist three components which is Kp, Ki and Kd. Each component has their own capability for controlling a dc motor. Kp can be used for increase the transient response of dc motor. We can set some values of Kp until get a an optimum system response. For the Ki, it was used for overcome the steady state error. Lastly, Kd is used to get a better response in achieving a set point of the controller by entering a value. By using a PID algorithm, adjusting can be easier by set up in the programming section and the real position of rotation dc motor will get through this programming. This PID algorithm will increase the transient response and reduced the steady state error that exists in the system.
