Abstract

An automobile servomotor controller includes a master side amplifier unit having an amplifier side control circuit for transmitting a designation signal and a slave side motor unit having an actuator side control circuit which controls driving of a motor by outputting an operation signal to a driving device depending upon said designation signal. The slave side motor unit is constructed by a same feedback control unit having a non-feedback control unit for inhibiting the operation of the motor until a target is changed by an input of a new designation signal with a target reached state and a feedback control unit for driving the motor to be reached to a target state by detecting a present value with a present value detecting device, and a control inhibiting signal for inhibiting the feedback control is individually provided to the designation signal transmitted from the amplifier side control circuit to the non-feedback control unit.

Claims

1. An automobile servomotor controller including a master side amplifier unit having an amplifier side control circuit for transmitting a designation signal through a communication line and a slave side motor unit having an actuator side control circuit which is connected to the master side amplifier unit through said communication line and controls driving of a motor by outputting an operation signal to a driving device depending upon said designation signal wherein,

said slave side motor unit is constructed by a same feedback control unit having a non-feedback control unit for inhibiting the operation of the motor until a target is changed by an input of a new designation signal with a target reached state and a feedback control unit for driving said motor to be reached to a target state by detecting a present value with a present value detecting device, the same feedback control unit including said present value detecting device, and

a control inhibiting signal for inhibiting said feedback control is individually provided to said designation signal transmitted from said amplifier side control circuit to said non-feedback control unit.

2. The automobile servomotor controller according to claim 1, wherein said master side amplifier unit includes an air-conditioning amplifier.

3. The automobile servomotor controller according to claim 1, wherein said slave side motor unit includes mode actuators provided corresponding to doors.

4. The automobile servomotor controller according to claim 1, wherein said feedback control unit includes an actuator.

5. The automobile servomotor controller according to claim 1, wherein said present value detecting device is provided apart from a center of a rotation shaft of a member to be turned by said motor, and is a PBR for detecting a position adjacent to a radial leading end portion of the member to be turned by the movement of the leading end portion along a turning locus.

6. The automobile servomotor controller according to claim 5, wherein said PBR is provided with a sliding groove extending in the tangential direction of the turning locus of the radial leading end portion of the member and a pair of holding projections slidable in the sliding groove.
