Control systems prototyping is usually constrained by model complexity, embedded system configurations, and interface testing. The proposed control system prototyping of a remotely-operated vehicle (ROV) with a docking hoop (DH) to recover an autonomous underwater vehicle (AUV) named AUVDH using a combination of software tools allows the prototyping process to be unified. This process provides systematic design from mechanical, hydrodynamics, dynamics modelling, control system design, and simulation to testing in water. As shown in a three-dimensional simulation of an AUVDH model using MATLAB™/Simulink™ during the launch and recovery process, the control simulation of a sliding mode controller is able to control the positions and velocities under the external wave, current, and tether forces. In the water test using the proposed Python-based GUI platform, it shows that the AUVDH is capable to perform station-keeping under the external disturbances. OPEN ACCESSRobotics 2015, 4 493

Remotely Operated Vehicle (ROV) teknologi observasi bawah laut di perairan selat Sunda yang telah dikembangkan memiliki keterbatasan dari segi manuver, yaitu hanya dapat bergerak vertical dengan kedalaman yang terbatas. Penelitian ini bertujuan untuk mendapatkan parameter hidrodinamika yang terbaik, yaitu matriks inersia, matrik coriolis, dan redaman hidrodinamika. Metode penelitian yang digunakan adalah metode fixed mesh, dimana diasumsikan fluida bergerak pada kecepatan dimana ROV bergerak dan model ROV diam (statik). Representasi gerak ROV dengan mengubah kemiringan ROV terhadap arah aliran fluida. Hasil dari penelitian adalah parameter hidrodinamika, yaitu (matriks inersia benda tega ROV), (Matriks koefisien untuk benda tega Coriolis), (inersia hidrodinamika), (matriks koefisien untuk hidrodinamika dengan Coriolis dan nilai sentripetal) memberikan koefisien inersia badan ROV kerangka rotasi terhadap titik pusat bumi. Sedangkan parameter hidrodinamika yaitu redaman hidrodiniamika menggambarkan gaya redaman hidrodinamika dan momen berkerja terhadap gerak relatif antara badan kendaraan dengan fluida

Abstract. The purpose of the present study is to investigate submarine rudder stern-plane configuration to obtain optimum manoeuvring characteristics. Three configurations are investigated: +, x and y configuration. The equations of motions were derived with the external forces and moments consist of contributions due to the hydrostatics, hydrodynamics and propeller thrust. To obtain the hydrodynamic coefficients and the hydrodynamic derivatives, the lift and drag were calculated using computational fluid dynamics (CFD). The equations of motions were numerically integrated using Eulerian method to obtain the turning circle. Results of the calculations show that the x-configuration gives the smallest tactical diameter, transfer and advance, which is considered as the most optimum rudder stern-plane configuration.
