Abstract
Brushless Direct Current (BLDC) motor controller umum digunakan pada kendaraan listrik. Institut Teknologi Sepuluh Nopember (ITS) Surabaya merupakan salah satu pusat pengembangan kendaraan listrik di Indonesia dengan mengembangkan komponen-komponen utama kendaraan listrik, salah satunya adalah BLDC motor controller. Namun BLDC motor controller ini masih memiliki kelemahan yaitu kondisi starting yang kasar akibat limit torsi atau limit arus yang membuat controller berhenti beroperasi ketika torsi atau arus mencapai limit.
Penelitian ini bertujuan untuk memperbaiki kelemahan tersebut dengan menganalisa respon transient controller pada pemodelan Look up Table Field Oriented Control (FOC) menggunakan Matlab/Simulink. Adapun langkah-langkah yang dilakukan ialah mencari persamaan Longitudinal Vehicle Dynamic untuk memperoleh nilai torsi, power, dan rpm maksimum sehingga dapat menentukan spesifikasi motor BLDC. Kemudian mendeteksi parameter dan menguji stabilitas model motor BLDC. Selanjutnya menentukan spesifikasi respon transient berupa nilai rise time, settling time, dan percent overshoot. Terakhir melakukan pemodelan FOC dengan look up table menggunakan Matlab/Simulink dan tuning parameter PI untuk memperoleh respon yang memiliki nilai spesifikasi respon transient sesuai target.
Pada pemodelan lookup table field oriented control dengan nilai parameter PI default (kp = 1 dan ki = 1) diperoleh hasil simulasi yang ditinjau dari respon rpm berupa nilai rise time sebesar 0,6445 detik, settling time sebesar 1,979 detik, dan nilai percent overshoot sebesar 0%. Sedangkan untuk hasil simulasi setelah melakukan proses tuning parameter (kp = 10 dan ki = 0,5) diperoleh nilai rise time sebesar 0,5522 detik, settling time sebesar 0,878 detik, dan percent overshoot sebesar 0%. Sementara pada pemodelan field oriented control diperoleh hasil simulasi yang ditinjau dari respon rpm berupa nilai rise time sebesar 0,6 detik, settling time sebesar 1 detik, dan percent overshoot sebesar 0%. Pada pemodelan field oriented control vedder diperoleh hasil simulasi yang ditinjau dari respon rpm berupa rise time sebesar 0,65 detik, settling time sebesar 1,5 detik, dan percent overshoot sebesar 0%. Sehingga dapat disimpulkan bahwa pemodelan lookup table field oriented control memperoleh hasil respon lebih baik dibandingan dengan pemodelan field oriented control, dan field oriented control vedder.

Brushless Direct Current (BLDC) motor controller is widely used on electric vehicle. Sepuluh Nopember Institute of Technology (ITS) Surabaya is one of the centers for developing electric vehicles in Indonesia develops main components in electric vehicles, one of which is the BLDC motor controller. However BLDC motor still has a disadvantage that a rough starting condition, this happens because there is a torque/current limit which disables the controller when the torque/current reaches the limit.
This study aims to correct this disadvantage by analyzing the transient response of controller on Look up Table Field Oriented Control (FOC) models using Matlab/ Simulink. The steps to be taken are looking for the Longitudinal Vehicle Dynamic equations to obtain the value of torque, power, and maximum rpm to determine the specifications of the BLDC motor. The next is detecting the BLDC Motor parameters and test the stability of the BLDC motor model. Next determines the specifications of the transient response in the form of rise time, settling time, and percent overshoot. The last is modeling the FOC on Look up Table using Matlab/Simulink and tuning the PI parameters to obtain a response that has a transient response specifications value according to the target.
Lookup table field oriented control model with PI default parameter values (kp = 1 and ki = 1) the simulation results are obtained in terms of the rpm response is 0.6445 s rise time, 1.979 s settling time, and 0% percent overshoot. While for the simulation results after tuning the parameters (kp = 10 and ki = 0.5) obtained 0.5522 s rise time, 0.878 s settling time, and 0% percent overshoot. field oriented control model obtained simulation results in terms of rpm response is 0.6 s rise time, 1s settling time, and 0% percent overshoot. Field oriented control vedder model obtained simulation results in terms of rpm response is 0.65 s rise time, 1.5 s settling time, and 0% percent overshoot. So it can be concluded that the lookup table field oriented control model has better response results than the field oriented control , and field oriented control vedder model.
