A specified controller (150) has a first-period generation unit (151) that determines first-period start timing for said controller (150) on the basis of second-period start timing for said controller (150). Other controllers (160) each have a first-period synchronization unit (161), a second-period correction unit (162), and the like. Each first-period synchronization unit (161) synchronizes the first-period start timing for that controller (160) with the first-period start timing for the abovementioned specified controller (150). Each second-period correction unit (162) corrects the second-period start timing for that controller (160) on the basis of the first-period start timing for that controller (160) so as to synchronize said second-period start timing with the second-period start timing for the specified controller (150). |
