Abstract
A control system includes: a piezoelectric element having a deformation amount that varies according to a magnitude of a drive voltage applied to the piezoelectric element; a base on which the piezoelectric element is arranged; a deformation sensor configured to detect a displacement of the base caused by deformation of the piezoelectric element and output the displacement as a displacement signal; and a drive device configured to apply the drive voltage to the piezoelectric element while adjusting the magnitude of the drive voltage so as to reduce a difference between a value of the displacement signal and a value of a setting signal.
