Operation Control

This paper designs a ship rudder system simulation device in order to serve the research of ship control better with the proportion of a real marine hydraulic rudder system, which can complete closed-loop experiments in the lab with the steering system. The rudder system simulation device mainly includes two parts, electric control system which uses PLC as core control unit, hydraulic system, and it can achieve both manual and automatic operation control mode.

Various methods of video-enhanced microscopy combine TV cameras with light microscopes creating images with improved resolution, contrast and visibility of fine detail, which can be recorded rapidly and relatively inexpensively. The AVEC (Allen Video-enhanced Contrast) method avoids polarizing rectifiers, since the microscope is operated at retardations of λ/9- λ/4, where no anomaly is seen in the Airy diffraction pattern. The iris diaphram is opened fully to match the numerical aperture of the condenser to that of the objective. Under these conditions, no image can be realized either by eye or photographically. Yet the image becomes visible using the Hamamatsu C-1000-01 binary camera, if the camera control unit is equipped with variable gain control and an offset knob (which sets a clamp voltage of a D.C. restoration circuit). The theoretical basis for these improvements has been described.
