Abstract

The use of sensorless technology at BLDC is mainly to improve operational reliability and play a role for wider use of BLDC motors in the future. This research aims to predict load changes and to improve the accuracy of estimation results of sensorless-BLDC. In this paper, a new filtering algorithm is proposed for sensorless brushless DC motor based on Ensemble Kalman filter (EnKF) and neural network. The proposed EnKF algorithm is used to estimate speed and rotor position, while neural network is used to estimate the disturbance by simulation. The proposed algorithm requires only the terminal voltage and the current of three phases for estimated speed and disturbance. A model of non-linear systems is carried out for simulation. Variations in disturbances such as external mechanical loads are given for testing the performance of the proposed algorithm. The experimental results show that the proposed algorithm has sufficient control with error speed of 3 % in a disturbance of 50 % of the rated-torque. Simulation results show that the speed can be tracked and adjusted accordingly either by disturbances or the presence of disturbances.

Abstract

Potensi sumber daya maritim terbesar sebagai sumber energi terbarukan untuk menghasilkan energi listrik adalah gelombang laut. Indonesia dengan garis pantai terbesar kedua memiliki potensi yang sangat besar dengan kerapatan mencapai 20 kW/m2 gelombang laut. Namun demikian belum ada yang mampu menghasilkan sistem pembangkit listrik yang optimal dalam mengubah energi gelombang laut menjadi energi listrik. Hal ini terjadi karena sebagian besar peneliti membangun sistem pembangkit listrik tenaga gelombang laut secara langsung. Dalam makalah ini akan dibangun model simulasi gelombang laut yang menjadi komponen utama dalam pengembangan sistem pembangkit listrik tenaga gelombang laut. Dengan adanya model simulasi gelombang laut secara visual dan tervalidasi, pengembangan sistem pembangkit tenaga gelombang laut menjadi lebih mudah dan optimal.Kata Kunci— Energi Terbarukan, Gelombang Laut, Pembangkit Listrik, PLTGL.
