Abstract
A vibration control device moves an object by controlling an actuator. The vibration control device controls a position and speed of the actuator, generates a model by modeling the object; and calculates an inverse system output based on the model and the control to provide positive feedback of a position of the object based on the inverse system output.
Claims12
A vibration control device for moving an object by controlling an actuator, the vibration control device comprising:
- an actuator controller configured to control a position and speed of the actuator;
- a linear system model of the object generated based on a wave equation;
- and
- a feedback unit configured to calculate a delay value of the object based on the linear system model, and configured to feed back a compensation value calculated based on the calculated delay value.
A vibration control system for moving an object by controlling an actuator, the vibration control system being provided with one or more information processing devices, the vibration control system comprising:
- an actuator controller configured to control a position and speed of the actuator;
- a linear system model of the object generated based on a wave equation;
- and
- a feedback unit configured to calculate a delay value of the object based on the linear system model, and configured to feed back a compensation value calculated based on the calculated delay value.
A vibration control method executed by a vibration control device for moving an object by controlling an actuator, the vibration control method comprising:
- controlling, by the vibration control device, a position and speed of the actuator;
- calculating, by the vibration control device, a delay value of the object based on a linear system model of the object generated based on a wave equation;
- and
- feeding back, by the vibration control device, a compensation value calculated based on the calculated delay value.
A non-transitory recording medium storing a program for causing a computer to execute vibration control, the computer being for moving an object by controlling the actuator, wherein the program causes the computer to execute:
- controlling a position and speed of the actuator;
- calculating a delay value of the object based on a linear system model of the object generated based on a wave equation;
- and
- feeding back a compensation value calculated based on the calculated delay value.
