Abstract
A control system of a linear actuator that is provided with a coil and a magnetic field unit, and is configured to drive a drive target object along a main axis, is configured to acquire position information of the drive target object or the linear actuator from an encoder and calculate the position information of the drive target object and the linear actuator, calculate a control amount to control drive of the linear actuator, based on position information of the drive target object and a target position to move the drive target object, determine an output level of the linear actuator based on the control amount, determine an output direction of the linear actuator, based on the control amount and the position information of the linear actuator, calculate a correction gain for correcting the control amount, based on the position information, the output level, and the output direction of the linear actuator, and correct the control amount by using the correction gain.
