This paper addresses the formation keeping of a network of Port-Controlled Hamiltonian(PCH) AUV multi-agent systems. The objective is solved by interconnecting agents with virtual couplings based on the internal principle, which can look into the energy consumption. Firstly, the controller for tracking estimated velocity is designed by ultilizing Hamiltonian theory. We assume that the desired velocity...
Seal is one of the most important characteristics for cylinders and suitable seal configuration will guarantee the long life cycle of the seal and the cylinder. Experiment is the only way which can demonstrate the best seal configuration in applications. In this paper, one approach is brought forward for testing the seal performance of cylinders with different seals configurations at the same load...
