Intelligent vehicles are complex distributed systems. An autonomous car combines vision, radar, lidar, proximity sensors, GPS, mapping, navigation, planning, and control. These components must combine into a reliable, safe, secure system that can analyze complex environments in real time and react to chaotic environments. Autonomy is thus a supreme technical challenge. An autonomous car is more...

This paper presents an adaptive formation control for a multiple Autonomous underwater vehicles (AUVs) using Lyapunov stability criterian. This controller considers the hydrodynamic parameter uncertainties of the AUVs. Simulations are performed considering three AUVs in a group and the results obtained demonstrate effective formation control of these AUVs while tracking a circular trajectory.

Development of automated tactical control in underwater vehicles is motivated by the growing need for both decision aids in manned vehicles, as well as for controllers in unmanned autonomous vehicles. While these systems may vary widely in architectural design, ultimately the system interacts with the world via a sequence of decisions or control variable assignments. The choice of these variabl...

Underwater environment poses a difficult challenge for autonomous underwater navigation. A standard problem of underwater vehicles is to maintain it position at a certain depth in order to perform desired operations. An effective controller is required for this purpose and hence the design of a depth controller for an unmanned underwater vehicle is described in this paper. The control algorithm...

The use of Unmanned Aerial Vehicles and Autonomous Underwater Vehicles as mobile sensor platforms in environmental science is growing. While the vehicles and sensor technology have reached maturity for practical operation, we observe that the potential of artificial intelligence allowing these devices to perform their tasks autonomously is not utilized. We give an overview of current applicatio...

We describe the methodology, tools and technologies for designing and implementing communication and control systems for networked automated or driver assist vehicles. In addressing design, we discuss enabling methodologies and our suite of enabling computational tools for formal modeling, simulation, and implementation. We illustrate our description with design, development and implementation ...

This paper proposes the result of hardware in the loop simulation (HILS) for performance evaluation about a small attitude heading reference system (AHRS) based micro electro mechanical system (MEMS) suitable for small unmanned underwater vehicle. Unmanned underwater vehicles (UUV) have many applications in scientific, military, and commercial area due to its autonomy and the navigation system ...

This article analyzes environmental security in the sphere of sea navigation, safety of navigation and tourism on the Adriatic Sea, bearing in mind that keeping marine environment healthy is one of fundamental factors of today’s national and international security. Likewise, secure underwater environment strengthens public security from hazards deriving from seafloor caused by human negligence ...

By virtue of their distinct features like autonomy, low signatures, no emissions, high specific energy etc., fuel cells could find a number of applications in the defence sector. Depending on the specific context, the requirement could be for a wearable, portable or distributed power supply. Powering unmanned aerial vehicles, ground vehicles and autonomous underwater vehicles form a separate re...

Underwater vehicles that use differential thrust for surge and yaw motion control have the advantage of increased maneuverability. Unfortunately, such vehicles usually don’t have thrusters/actuators to control the lateral movements. Hence, they fall into the underactuated vehicle category. The goal of the work in this thesis is to develop an autonomous control system for a differential thrust u...
