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 creates a physical model based on displacement caused by application of an external load to the actuator; generates a first control instruction to the motor such that the actuator generates the displacement according to the physical model; determines a spring constant; generates a second control instruction to the motor so as to generate drive force calculated based on a product of the spring constant and the displacement generated in the actuator; and selects and validates one of the first and second control instructions.
