Abstract
A control apparatus for a machine that can be operated at high precision in a stable control state is provided by driving a movable body with control parameters suited to the mechanical state. A control parameter calculation circuit is provided to obtain control parameters for a drive apparatus control circuit for driving actuators in accordance with the conditions of actuator rotational velocity, the orientation of the movable body, and the position of the movable body, and a control parameter K for the drive apparatus control circuit is varied.
Claims2
A control apparatus for a feed driving system, comprising:
- a drive apparatus control circuit for driving a movable body using an actuator and freely changing the position and orientation of the movable body with respect to a holding base;
- and
- a numerical control apparatus for providing a command for controlling said actuator to said drive apparatus control circuit;
- wherein
- said control apparatus for the feed driving system, includes a control parameter calculation circuit for newly calculating control parameters for the drive apparatus control circuit in accordance with a feed velocity of the actuator and the position or the orientation of the movable body;
- and
- control parameters for the drive apparatus control circuit are varied in accordance with a travel velocity of the movable body and the position or the orientation of the movable body based on the control parameters newly calculated by the control parameter calculation circuit.
