Abstract
PURPOSE: To remove the pulsation of the amount to be controlled by a sampling control instruction while maintaining a control accuracy by outputting the sampling control instruction this time only when the deviation between a control instruction at this time sampling time and a control instruction at previous sampling time exceeds predetermined value.
CONSTITUTION: When a speed detecting circuit 2 operates at every predetermined period via a timing pulse generator 1 to thereby detect a motor speed and thus completes the detecting operation, a control current calculating circuit 3 operates to calculate the control current calculated value ic. An effective control current detecting circuit 5 compares the value ic with the control current value io outputted at present every time the value ic varies to thereby obtain a deviation Δic. When the deviation Δic is higher than predetermined set value, the value ic is outputted as a control current io to a motor control circuit 4. When it is lower than the predetermined set value, the control current io is not varied.
