Research of High Positional Accuracy of Manipulator Crane for Floating Nuclear Power Plants

This paper builds a mathematics model of the positioning accuracy of the manipulator crane for floating nuclear power plants according to the manipulating process,and particularly analyzes every part relevant to positioning accuracy.On that basis,a kind of high positioning accuracy technology is provided:the technology to combine the open-loop and the close-loop compensating.This technology can increase the positioning accuracy of floating nuclear power plant manipulator evidently,and satisfies the high positioning accuracy of floating nuclear power plant manipulator crane.
