Inadequate of Control of the Modern Autonomous Underwater Vehicles (AUV)
Autonomous Underwater Vehicles (AUV) are robotic and programmable vehicles which can drive, drift, or glide through water without real time human control; the use to which they are put depends on their design (Afatarly et al., 2020). They have become common devices for use in performing complex work on platforms that are costly and large. They are also preferred for their significant long and short term cost efficiency. The miniature robotic machines face navigation and control challenges which can be addressed through a variable-fuzzy-predictor-based predictive control approach.
The machines face control issues due to challenges in tracking their trajectory while in water. In the subsea sector, there is no capability to strap on a GPS as in the case of air and land machines so that the machines’ locations and direction can be tracked on real-time (Williams et al., 2016). As such, tracking the machines is done through inertial technologies as well as sensor fusion, in which different sensors are used to measure and observe individual states that fuse so that they sort out the navigation issue and enable tracking.
The loss of GNSS and GPS in water is caused by the electromagnetic capacity of water. As such, this is compensated in the observation class AUVs by ensuring the machines are adequately equipped with a navigation system, one or more (Salhaoui et al., 2020). The navigation system helps in calculating the position of the machine through dead-reckoning from the machines’ last available information on GPS or GNSS waypoint. This is the approach that is used to track the trajectory and position of the AUVs in water.
Notably, each of the individual sensor systems used in the machine has various limitations; rate drops, dropped signals, and simple errors. However, it is possible to create a fully integrated platform with sensors for aiding in heading, depth, and assistance for navigation (Praczyk, 2020). The system can thus help in improving reliability and accuracy of the inertial solution that is used for control of the miniature machines. Currently, the machines face challenges in control due to the inefficiency of the approach used.
