Abstract
A stored control program includes subperiods into which an operation period from a start to an end of an operation of an automated manufacturing machine is divided. Each subperiod is assigned with an actuator to act and action information about the actuator. The subperiods are sequentially selected one by one as a control target, and feedback control is performed on an action of the actuator assigned to the selected subperiod. This reduces the number of actuators controlled at the same time for controlling the operation of an automated manufacturing machine including many actuators. The control program can thus be executed promptly with an operation control apparatus having ordinary processing capability.
Claims6
An operation control apparatus for an automated manufacturing machine including a plurality of actuators, the operation control apparatus being configured to control an operation of the automated manufacturing machine by causing the plurality of actuators to act in accordance with a prestored control program, the apparatus comprising:
- a control program storage storing operation data as the control program, the operation data describing the operation of the automated manufacturing machine, the operation data including a plurality of subperiods into which an operation period from a start to an end of the operation of the automated manufacturing machine is divided, each of the plurality of subperiods being assigned with an actuator of the plurality of actuators to act and action information about the actuator;
- one or more processors configured to select one of the plurality of subperiods as a control target subperiod;
- the one or more processors configured to extract, from the control program, a control target actuator being an actuator of the plurality of actuators to be controlled in the control target subperiod and control target action information being the action information about the control target actuator;
- and
- a controller configured to perform feedback control on an action of the control target actuator to cause the control target actuator to act in accordance with the control target action information,
- wherein upon completion of the feedback control on the control target actuator assigned to a current control target subperiod, the control target subperiod selector newly selects, as the control target subperiod, a subperiod of the plurality of subperiods subsequent to the current control target subperiod.
An operation control method for an operation control apparatus to control an operation of an automated manufacturing machine including a plurality of actuators, the operation control method being implementable to control the operation of the automated manufacturing machine by causing the plurality of actuators to act in accordance with a prestored control program, the method comprising:
- loading the control program describing the operation of the automated manufacturing machine, the control program including a plurality of subperiods into which an operation period from a start to an end of the operation of the automated manufacturing machine is divided, each of the plurality of subperiods being assigned with an actuator of the plurality of actuators to act and action information about the actuator;
- selecting one of the plurality of subperiods as a control target subperiod;
- extracting, from the control program, a control target actuator being an actuator of the plurality of actuators to be controlled in the control target subperiod and control target action information being the action information about the control target actuator;
- and
- performing feedback control on an action of the control target actuator to cause the control target actuator to act in accordance with the control target action information,
- wherein the selecting the control target subperiod includes newly selecting, as the control target subperiod, a subperiod of the plurality of subperiods subsequent to a current control target subperiod upon completion of the feedback control on the control target actuator assigned to the current control target subperiod.
A non-transitory computer-readable storage medium storing a program for an operation control apparatus to control an operation of an automated manufacturing machine including a plurality of actuators, the program causing a computer included in the operation control apparatus to implement an operation control method to control the operation of the automated manufacturing machine by causing the plurality of actuators to act in accordance with a prestored control program, the program causing the computer to perform operations comprising:
- loading the control program describing the operation of the automated manufacturing machine, the control program including a plurality of subperiods into which an operation period from a start to an end of the operation of the automated manufacturing machine is divided, each of the plurality of subperiods being assigned with an actuator of the plurality of actuators to act and action information of the actuator;
- selecting one of the plurality of subperiods as a control target subperiod;
- extracting, from the control program, a control target actuator being an actuator of the plurality of actuators to be controlled in the control target subperiod and control target action information being the action information about the control target actuator;
- and
- performing feedback control on an action of the control target actuator to cause the control target actuator to act in accordance with the control target action information,
- wherein the selecting the control target subperiod includes newly selecting, as the control target subperiod, a subperiod of the plurality of subperiods subsequent to a current control target subperiod upon completion of the feedback control on the control target actuator assigned to the current control target subperiod.
