This paper considers the finite-time controller design for wheeled mobile robots. After the mobile robot dynamics have been transformed into an advantageous form, called the heisenberg form, a finite-time controller is designed in order to promulgate the practical stability of the system. The desired stability property of the closed-loop system is provided by applying a homogeneous sliding mode controller,...
This paper proposes a distributed control law for three mobile autonomous agents to shape an acyclic triangle formation. Agents move themselves autonomously in two orthogonal axes to pursue and maintain the prescribed distances to their co-leaders. The dynamical system approaches exactly to the desired edge lengths and the orientation of the triangle in any initial condition except initial collocation...
In this paper, we consider the problem of navigation and guidance of a Dubins-like wheeled robot towards a steady or maneuvering target with range-only information. We propose a range-based sliding mode controller through which the robot follows a target with a constant speed while preserving a predefined range margin from the target. Mathematically rigorous proof of convergence and stability of the...
This paper presents a dynamic region following formation control method for a swarm of robots. In this control strategy, a swarm of robots shall move together as a group inside a dynamic region that can rotate or scale to enable the robots to adjust the formation. Various desired shapes can be formed by choosing appropriate functions. Unlike existing formation control methods, the proposed method...
