Abstract
An apparatus includes a command generation portion that generates the command signal, and a first monitoring portion that monitors an abnormality relating to actuation of the actuator control apparatus. The actuator control apparatus includes a control portion and a second monitoring portion. The control portion generates a control signal for controlling operation of the actuator in accordance with the above-described command signal. The second monitoring portion monitors an abnormality that relates to actuation of the actuator control apparatus and that is different in type from an abnormality monitored by the first monitoring portion.
Claims3
A fly-by-wire flight actuator control system comprising:
- an operation control apparatus to control a device driven by an actuator by generating a command signal for commanding operation of the device, the operation control apparatus includes a command generation portion to generate the command signal for commanding operation of the device, and the operation control apparatus further includes a first monitoring portion;
- a communication bus;
- and
- an actuator control apparatus interfacing with the operation control apparatus via the communication bus to control the actuator in accordance with the command signal received from the operation control apparatus;
- wherein the actuator control apparatus includes a control portion to generate a control signal for controlling operation of the actuator in accordance with the command signal received from the operation control apparatus, and a second monitoring portion to monitor an abnormality related to actuation of the actuator control apparatus, wherein the second monitoring portion is to monitor an abnormality of a different type than an abnormality monitored by the first monitoring portion,
- wherein the first monitoring portion of the operation control apparatus is configured to monitor an abnormality relating to actuation of the control portion of the actuator control apparatus,
- wherein the first monitoring portion monitors an abnormality relating to actuation of the control portion by performing the same process as the control portion, and comparing a result of the process with a result of the process performed by the control portion, and;
- wherein the second monitoring portion monitors at least one of an abnormality of a power source for supplying power for actuating the actuator, and an abnormality of a current supplied via the actuator control apparatus for actuating the actuator.
