Abstract
A position control device includes a position detector that detects a position of an object to be controlled; a target generator that outputs a target velocity and a target position of the object to be controlled; a first calculator that calculates a control amount for causing the object to be controlled to track the target position; a second calculator that calculates a control amount for controlling the velocity of the object to be controlled, to be at the target velocity; a control signal output unit that outputs a control signal according to a total control amount obtained by the first and the second calculators; and a storage unit that stores an attitudinal change correction amount. The second calculator acquires the attitudinal change correction amount stored in the storage unit, adds the attitudinal change correction amount to the control amount to correct the control amount, and outputs the corrected control amount.
