摘要：Automatic control of DC servo motor in terms of rotation angle has played a vital role in theadvance Electromechanical Engineering. Nowadays, the automatic process of motor controlusing a Personal Computer (PC) is commonly used. The controllers are designed to interfacebetween a Computer and Motor. This paper presents the implementation of PICMicrocontroller with Graphical User Interface (GUI) in Matlab to track the rotational angle ofDC servo motor. The movement of slider on GUI will act as an input signal into theMicrocontroller to change the rotation angle. A simulation on the performance of the systemhas been carried out using Proteus software interfaced with Matlab and the controller was testedon real-time application. Results show that the use of PIC Microcontroller and GUI in Matlabis an advantage solution to control the rotational angle.
