Abstract

PURPOSE:To enhance stability without narrowing the operational bandwidth of the system, by negatively feeding back the deviation between the output of a motor driving system including noises and the output of the system realized by a highly accurate and very fast logic operation circuit and the like to the motor driving circuit. CONSTITUTION:A noiseless control element G2 is constituted by an A/D converter AD, a high speed processor HP having a very fast, very accurate operating function, and a D/A converter DA. The program processing of the high speed processor HP is executed based on a speed command value VT. The result and the output of a speed sensor T are compared in a comparator DA1, and the output of the comparator DA1 is given to a comparator DA2 as a speed feedback signal. In this constitution, the system can be stabilized without narrowing the operational bandwidth of the system.
