The dynamic positioning (DP) ship maintains its position and heading by active thrusters. Some measurements of the ship motion variables can be obtained from certain reference sensor systems. However, the other measurements may be expensive or impossible to be obtained, such as ship velocity and acceleration. Fortunately, they can probably be estimated using the available measurements and the ship...
To meet the requirements of the tactical targets, in the progress of the missiles' flight, we often give the related parameters a range to make the targets to extreme. In this paper, we use variable Calculus to learn about the variation of the deflection in missiles' flight trajectory and the method that can make the missiles reach a certain height in the shortest time. Then with the help of the software-MATLAB,...
For a traveling crane, various control methods such as fuzzy control and optimum control are studied. In the control of an actual traveling crane, it is important to accurately stop the crane at the desired position by positioning control and anti-sway control. In this paper, we designed a control system using an H/sub 2/ controller reduced by the minimal order observer, which is a new approach. The...
