Abstract

PURPOSE: To stably control a DC motor by integrating a current feedback signal at everp predetermined period, holding it, then digitally converting it from analog value, and controlling the current with average current value of the signal, thereby effectively extracting the average value even from the current value including ripple.
CONSTITUTION: A field current value or armature current value Ia is normalized by a normalizing circuit 118 in a circuit for driving and controlling a DC motor under digital control, and is then integrated by an integrating circuit 201. Processing sequence is stored in advance in a processing circuit 122a for producing a series of timing signals, sampling holding start signal SH is applied to a multiplexer 119a via an address latching circuit 119a at every predetermined period, to hold the integrated value in the holding circuit 119b. The held value is digitally converted by an A/D converter 119c, and is inputted as a current average value to a controlling circuit. The integrating circuit 201 is cleared by a clearing circuit 202 at the same period after being held as the integrated value.
