| Summary: | Autonomous underwater vehicle or commonly abbreviated as AUV is a vehicle
that can move under water, which is also known as an unmanned undersea vehicle
(UUV). One type of AUV is a hybrid underwater glider (HUG) where the vehicle
is designed in such a way as to be able to carry out missions in water with less
power consumption so that it can last a long time in carrying out missions. In this
research mathematical design is carried out to produce modeling in the longitudinal
plane of the HUG vehicle which will be tested based a simulation using the
MATLAB / Simulink. The parameters used in the model for longitudinal plane are
obtained by computational fluid dynamics (CFD) method so that it has been
simulated with various movements according to the mission of the vehicle. In the
simulation, a nonlinear model is used which is given input as variations value of the
actuator that modeled as input for longitudinal plane including the main thruster as
surge actuator, moving mass for pitch and buoyancy engine movements to make
the vehicle sink where the simulation is an open loop system that derived translation
position, speed and rotation. PID Controller are designed for steer and depth control
using inner and outer loop method from controller design so that the vehicle can
manuveuring to desire position. |
