Abstract
A drive system includes an actuator that is driven by a motor to generate displacement, a driver that drives the motor, and a controller that gives a control instruction to the driver. The controller includes a model creation unit that creates a physical model based on displacement caused by application of an external load to the actuator and an instruction generating unit that generates a control instruction such that the actuator generates displacement according to the physical model.
Claims20
A drive system comprising:
- an actuator that is driven by a motor to generate displacement;
- a driver configured to drive the motor;
- and
- a controller configured to give a control instruction to the driver,
- wherein the controller is configured to:
- create a physical model based on displacement caused by application of an external load to the actuator;
- and
- generate the control instruction such that the actuator generates displacement according to the physical model.
A control method for an actuator that is driven by a motor to generate displacement, the control method comprising:
- creating a physical model based on displacement caused by application of an external load to the actuator;
- and
- controlling the motor such that the actuator generates displacement according to the physical model.
A non-transitory storage medium encoded with a computer-readable control program for controlling an actuator that is driven by a motor to generate displacement, the control program causing one or more processors to perform:
- creating a physical model based on displacement caused by application of an external load to the actuator;
- and
- controlling the motor such that the actuator generates displacement according to the physical model.
