| Abstract: | The variation of the temperature has great influences on the precision of a positioning stage with large stroke and high precision.A kind of real-time temperture compensation method based on the thermal expansion model of the positioning stage was put forward.The experimental result shows that the compensation method proposed can reduce the root mean square value of stage drifting caused by temperature variation more than 80%.The method is simple,reliable,easier to realize a real-time temperature compensati... |
