Telah dibuat sistem pengendali keseimbangan bola berbasis PC. Sistempengendalian dilakukan dengan PC yang kemudian diterjemahkanmicrocontroller dan selanjutnya di kirim ke motor DC untuk diproses agar didapat hasil yang kita inginkan. Sistem pengendalian di pc menggunakan metode PID, dari PID akan menghasilkan angka-angka (set point) yang akan dikirim ke microcontroller. Pengendalian pada microcontroller adalah pada PWM. Set point yang telah ditentukan oleh PID dimasukkan ke PWM. PWM akan menghasilkan kecepatan motor sesuai dengan yang ditentukan PID, setelah itu tegangannya di kirim ke motor DC. Maka motor DC akan bergerak ke kiri atau ke kanan tergantung set point yang ditentukan oleh PID. Bola akan bergerak lalu berhenti di titik tertentu sesuai dengan set point yang telah ditentukan. Kata kunci-PID, PWM, Motor DC, Microcontroller

Had been done the ball balancing control’s system based on PC. The System control

was carried out with PC that afterwards was translated microcontroller and

then sent to DC motor to be processed in order to be gotten by results that were

wanted by us. The control system in pc used the PID method, from PID will produce

figures (the set point) that will be sent to microcontroller. The control in microcontroller

was to PWM. Set point that was determined by PID was put into

PWM. PWM will produce the speed of the motor in accordance with that was determined

by PID, after that his voltage was sent to the motor of DC. Instead of the

DC motor will move to left or to right depend the set point that was determined by

PID. Ball will move then stopped in the certain point in accordance with the set

point that was determined.
