Fuzzy-based NC application in machine tools with efficient analog CMOS circuits

For high speed applications, analog techniques are known to be faster than digital techniques with significantly less power consumption and silicon area requirements. This paper provides a CMOS realization of current-mode general-purpose fuzzy hardware and a design applied for superior motion control in NCs (numerical controls) used in the machine tool industry. Nowadays, among other control systems, one of the major goals in machine tool systems is to integrate such systems which have the intelligence to determine optimal conditions for producing accurate and smooth workpiece. In this paper, initial research using efficient analog CMOS circuitry to optimize spindle motor speed in machine tools is described.
