Abstract
An actuator control apparatus includes an analog-digital conversion circuit, a servo circuit, a sampling circuit, and a driving circuit. The analog-digital conversion circuit is configured to sample a position detection signal with a first sampling period, convert the sampled signal into a digital signal, and output the digital signal, the position detection signal outputted from a position sensor corresponding to a position of a control target. The servo circuit is configured to calculate a displacement amount, by which the control target is to be displaced by an actuator, and output first servo control data corresponding to the calculated displacement amount, based on the position detection signal converted into the digital signal. The sampling circuit is configured to linearly interpolate the first servo control data, and output second servo control data sampled with a second sampling period shorter than the first sampling period.
