An information processing device includes: a correction coefficient holding unit configured to hold a correction coefficient which is a ratio between the position of a control target at a start time of control operation, and a detection signal indicating the control result of the control target; an initial-value-compensation matrix holding unit configured to hold an initial-value-compensation matrix for performing compensation of the initial value of a control computing unit for computing control output for controlling the control target from the detection signal based on the position and speed of the control target; and an initial-value generating unit configured to correct the position and speed of the control target at a start time of control operation with the correction coefficient, and employ the position and speed of the control target after correction, and the initial-value-compensation matrix to generate an initial-value-compensation value for compensating the initial value of the control computing unit.
