Abstract
A synchronous controller includes a command controller for outputting action commands to actuator controllers for synchronously controlling respective corresponding actuators. Each actuator controller includes an interrupt controller and a corresponding internal counter. One interrupt controller is designated as a master and the remaining interrupt controllers are designated as slaves. The master interrupt controller activates an interrupt signal on a bus based on the count value of its corresponding internal counter and resets the counter while the slave interrupt controllers concurrently reset their corresponding internal counters upon detecting the interrupt signal on the bus.
