Abstract
A machine control system includes a first movable element configured to be driven by a first motor, a second movable element configured to be driven by a second motor which is connected to the first motor so that a jerk to be generated by the first motor is applied to the second movable element, and control circuitry configured to generate a first control command to control the first motor and to generate a second control command to control the second motor according to the jerk.
Claims17
A machine control system comprising:
- a first movable element configured to be driven by a first motor;
- a second movable element configured to be driven by a second motor which is connected to the first motor so that a jerk to be generated by the first motor is applied to the second movable element;
- and
- control circuitry configured to generate a first control command to control the first motor and to generate a second control command to control the second motor according to the jerk to be generated by the first motor so as to suppress a vibration to be applied to the second movable element due to the jerk to be generated.
1 more element
A machine controller comprising:
- control circuitry configured to generate a second control command to control the second motor according to a jerk to be generated by a first motor and to be applied to the second motor,
- wherein the control circuitry is configured to generate the second control command in which a vibration suppression command generated based on the jerk is added to a normal control command to control the second motor.
