Abstract

PURPOSE:To stabilize a control system by adding a circuit which applies a transmission amount inversely proportional to a power coefficient proportional to the electric impedance of an actuator drive circuit to a circuit which applies a feedback coefficient. CONSTITUTION:A control voltage is applied to an input terminal 1, the control voltage is amplified through an FET2 via a control amplifier 4, and a motor 5 is driven by the output of the amplifier. The output voltage proportional to the speed of a DC tachometer generator 6 coupled directly to the motor 5 is applied to the input terminal of a feedback amplifier 7. Necessary transfer function is applied by the amplifier 7, the output is applied to the source electrode of the FET2, is superposed with a control signal via the FET2, thereby forming a speed feedback loop. A transmission amount inversely proportional to the power coefficient to the electric impedance of an actuator drive circuit is applied to the amplifier 7.
