Analysis of Measurement System as a Mechatronics System

摘要

The paper deals with the use of a mechatronic approach to an angle measuring system application where the objects to be measured are circular raster scales, rotary encoders and coded scales. The key task of the measuring system is to determine the bias of the angle measuring standard as a circular scale and to use the results for both error correction and achieving an improvement in accuracy of metal cutting machines, coordinate measuring machines, robots, etc. The technical solutions are given, together with the application of active materials for smart piezoactuators implemented in several positions of the angular measuring equipment. The mechatronic measuring system is analysed as a complex integrated system and some of its elements can be used as separate units. All these functional elements are described and discussed in some detail in the paper using diagrams and graphs illustrating the errors present, together with examples of microdisplacement devices using mechatronic elements of this type.
