<P>PROBLEM TO BE SOLVED: To provide a feedback control method that implements improved control precision. <P>SOLUTION: The multiplication of a control output signal (speed command) from PI control 11 by a predetermined pulse 31 can pulse the control output at intervals shorter than control cycles to increase the apparent output resolution and thus implement precise feedback control. <P>COPYRIGHT: (C)2008,JPO&INPIT |
