Modified adaptive observer based backstepping control system for dynamic positioning of ship is proposed. As an improvement, the adaptive observer takes the first-order wave frequency model and the bias term which represent the slowly varying environmental disturbances and the unmodeled dynamics. Thus, the wave-frequency motions are filtered out, and only the reconstructed low-frequency motions are...
In order to improve the traditional injection technology and equipment, the totally electrical screw-rotated injection equipment and method are proposed. This paper points out structure of this new equipment, working principle, and key problems need to be solved when using screw-rotated injection. This new equipment makes several breakthroughs and expands the application space for injection technology.
