Abstract
A control device includes a first processor that acquires a synchronization signal that is generated every first period, and a second processor that generates a second period that is obtained by dividing the first period by n (n≥1), generates a control signal, using a timer, every third period that is obtained by dividing the second period by m (m≥2), where at least one of a plurality of control signals generated in the first period is a control signal that should be synchronous with the synchronization signal, and in a case where occurrence of an error between timings of the synchronization signal and the control signal that should be synchronous with the synchronization signal is detected, the second processor corrects the error by temporarily changing a width of the timer that is to be started at next and later times.
