Abstract:
1. An actuator control system comprising an operation control apparatus that controls operation of a device driven by an actuator by generating a command signal for commanding operation of the device, and an actuator control apparatus that controls the actuator in accordance with the command signal, wherein said operation control apparatus and said actuator control apparatus are connected via a digital data bus; the actuator control apparatus includes a first control portion that generates a control signal for controlling operation of the actuator in accordance with the command signal, a second control portion that generates a control signal for controlling operation of the actuator in accordance with the command signal and that is different in design from the first control portion, and a switching unit that switches a state of connection between the actuator and each of the first control portion and the second control portion such that one of the control signals generated by the first control portion and the second control portion is output to the actuator to control operation of the actuator, the operation control apparatus includes a command generation portion that generates the command signal, a first monitoring portion that monitors an abnormality relating to operation of the first control portion and a second monitoring portion that monitors an abnormality relating to operation of the second control portion, and the switching unit switches, when an abnormality is detected by one of the first monitoring portion and the second monitoring portion, the state of connection from a state where one of the first control portion and the second control portion is connected to the actuator to a state where the other of the first control portion and the second control portion is connected to the actuator, wherein the actuator control apparatus further includes a third monitoring portion that monitors an abnormality that relates to operation of the actuator control apparatus and that is different in type from an abnormality monitored by the first monitoring portion and the second monitoring portion.
