Formation tracking and transformation are the key problems in formation control of multi-AUV (autonomous underwater vehicle) system. In this paper, an improved self-organizing map (SOM) neural network method is proposed for solving the formation issues of a group of autonomous underwater vehicles (AUVs). All the AUVs in the formation are treated equal to be the leaders or the followers. The desired...
Four nitride coatings, TiN, TiAlN, AlTiN and CrAlN were deposited on YG6 (WC+6wt.% Co) cemented carbide by cathodic arc-evaporation technique. The friction and wear properties were investigated and compared using ball-on-disc method at high speed with SiC ball as a counter material. The tests were evaluated by scanning electron microscopy, X-ray diffractometer, energy dispersive X-ray, micro hardness...
This paper deals with a directed formation control problem of three agents moving in the plane, where the agents have a cyclic ordering with each one required to maintain a nominated distance from its neighbor. The agent dynamics under consideration is a double integrator. Firstly, a directed formation control law based on the knowledge only of the direction of its neighbor, is designed by using the...
This paper deals with the distributed formation control problem of multiple nonholonomic mobile robots. By using smooth time-varying feedback control approach and graph theory, a distributed formation control law is designed, which can achieve formation of a system of multiple nonholonomic mobile robots. Based on potential function, a control law for obstacle collision avoidance is constructed. Simulation...
