Abstract
Motor DC, sebagai salah satu mesin listrik yang banyak digunakan di industri, penggunaannya banyak digantikan dengan motor Brushless DC (BLDC). Motor Brushless DC banyak dioperasikan di dunia industri, terutama industri yang mudah terbakar dan efisiensinya lebih tinggi daripada motor industri. Dalam berbagai penggunaan motor Brushless DC sering kali diperlukan kecepatan yang stabil seiring dengan beban yang berubah-ubah. Padahal untuk membuat kecepatan motor Brushless DC stabil tidaklah mudah, karena tidak adanya brush pada motor Brushless DC. Oleh karena itu diperlukan metode pengaturan kecepatan motor Brushless DC agar dapat mempertahankan kecepatan motor selama motor itu digunakan.
Pengendalian kecepatan pada motor Brushless DC bisa dilakukan dengan berbagai metode. Dalam Tugas Akhir ini metode yang digunakan adalah metode PID Self Tuning Reguator. Proportional Integral Derivative controller atau biasa disebut PID merupakan kontroler mekanisme umpan balik yang biasanya dipakai pada sistem kontrol industri. Dipilih kontroler PID karena kontrol yang paling sering dipakai. Self Tuning Regulator merupakan salah satu skema kontrol adaptif untuk kasus regulator.
Pada kondisi plant dengan tambahan beban sebanyak 50% hingga 100% pada beban damper dan beban inersia. Respon kecepatan memiliki nilai Root Mean Squared Error (RMSE) sebesar 0,0214. Dengan nilai RMSE yang relatif kecil atau mendekati 0, maka dapat disimpulkan bahwa perancangan Kontroler berhasil.
========================================================= DC Motor, one of most used electrical machinery in industry, currently is replaced with Brushless DC Motor (BLDC). Brushless DC Motor mostly operated in extreme industrial area such as flammable environment. Besides, Brushless DC motor has higher level of efficiency than regular industrial motor. In practice, Brushless DC motor need to be operated in stable velocity, whatever the amount of the load is. However, to keep the velocity stable is not a simple thing because of the absence of brush. Thus, we need a method to control the velocity of the motor to keep it in a stable velocity during operation.
There are various method could be applied for this case, and in this final project, PID method will be applied. Proportional Integral Differential or abbreviated PID is a feedback mechanism controller which generally used in industrial control system. Thus, PID controller is chosen. In this final project, PID method is expected to control and to keep the stability of the Brushless DC motor velocity. Self Tuning Regulator itself is an adaptive scheme in the regulator case.
With an additional load of 50% to 100% on the dampening load and inertia load. The speed response has a Root Mean Squared Error (RMSE) value of 0.0214. With the RMSE value is relatively small or close to 0, it can be concluded that the controler designing is successful.
