DRIVING APPARATUS, LIGHT SOURCE DRIVING APPARATUS, LIGHT SOURCE APPARATUS, PROJECTION APPARATUS, AND DRIVING METHOD, SUITABLE FOR DRIVING LOAD IN WHICH VALUE OF PHYSICAL QUANTITY AS CONTROLLED OBJECT PERIODICALLY CHANGES

摘要

A driving apparatus drives a load so as to periodically change a physical quantity as a controlled object. The apparatus includes a calculation unit configured to calculate a deviation between the targeted value and a detection value detected by the detection unit, a storage unit configured to store past deviations calculated by the calculation unit, a determination unit configured to determine a manipulative variable corresponding to the physical quantity, by referring to a past deviation before a predetermined period, which has been stored in the storage unit, and a driving unit configured to drive the load, based on the manipulative variable determined by the determination unit.
