ESTIMASI GERAK SURGE, HEAVE DAN PITCH AUTONOMOUS UNDERWATER VEHICLE DENGAN ENSEMBLE KALMAN FILTER (EnKF)

Teguh Herlambang, Subchan Subchan, Hendro Nurhadi

Abstract


Autonomous Underwater Vehicle (AUV) atau wahan air tanpa awak merupakan salah satu jenis robot bawah air yang relatif flexibel untuk eksplorasi bawah laut dan peralatan sistem pertahanan bawah laut. AUV dapat dikendalikan untuk bergerak dengan enam derajat kebebasan (6-DOF). Pengendalian AUV dibagi menjadi dua yaitu kendali kecepatan dan kendali agar mengikuti lintasan yang diinginkan.  Kendali AUV agar mengikuti trajectory yang diinginkan ini biasa disebut dengan sistem navigasi atau Estimasi trajectory.  Pada penelitian ini dikembangkan sistem navigasi untuk gerak menyelam dengan model 3-DOF yaitu gerak surge, heave dan pitch dengan metode Ensemble Kalman Filter (EnKF). Hasil simulasi menunjukkan bahwa metode EnKF dapat digunakan sebagai estimator gerak 3-DOF dengan menghasilkan error 0.011 m/s untuk gerak surge dan 0.009 m/s untuk gerak heave serta 0.004 rad/s untuk gerak pitch, sedangkan error posisi menyelam 0.01 m.
