Abstract

PURPOSE:To enable valve opening of being adjusted stably without the use of a DC servo motor by generating a valve body opening and closing speed instruction according to an opening and closing error, calculating a speed error between the speed instruction value and an actual valve body opening and closing speed and controlling a motor according to the speed error. CONSTITUTION:When there is an error between an instructed valve opening Ko and a current valve opening K, the error Ke therebetween and opening and closing speed instructions OVo, CVo according to said error Ke are calculated by a speed instruction operating circuit 38 and a torque instruction It according to an error Ve between those value and an actual opening and closing speed V is calculation by the torque instruction operating circuit 42 of an AC servo amplifier 40. In addition, after the primary current I1 of a motor 18 required to generate the torque instruction It is calculated by the vector operating circuit 43 of the AC servo amplifier 40, a motor 18 is controlled for driving mode thereof to supply the primary current It from a current supply control circuit 45.
