Heading control of an autonomous underwater robot with sliding mode and backstepping techniques

Abstract

The variation of the parameters of the autonomous underwater robot (inertia, hydrodynamics), external disturbances, the non-linearity of the model to be controlled, and measurement errors due to the sensors are the factors that have a negative influence on the robot's trajectory following. Autonomous submarine. A control law that takes these different factors into account would be an adequate solution to this control problem. This work is a simulation study of some advanced control techniques for controlling the heading of an autonomous underwater robot. We have developed two robust command structures. One of them is based on the sliding-mode control, which is applied to the considered model. The other is based on the control of backstepping. Several simulation tests were done to see how the robot moved after the two control methods were used.

An overview of emerging trends in robotics and automation

“…Sensors, global positioning systems (GPS), and artificial intelligence are often utilized by these vehicles in order to traverse their surroundings and make judgments. Motor vehicles that drive themselves and other autonomous vehicles have the potential to revolutionize transportation by lowering the number of accidents, enhancing the flow of traffic, and lowering the need for parking places [3], [4], [37], [40], [41].…”

“…Several major technology companies and automobile manufacturers are making significant investments in the development of autonomous vehicles, which is leading to improvements in ride-sharing services and solutions for last-mile delivery. The way in which we carry both people and things is going to be fundamentally altered by autonomous cars as regulations continue to develop to accommodate new technology [3], [4], [25], [37], [40], [41].…”
