摘要：A distributed hydraulic system having a plurality of hydraulic functions eachincluding a hydraulic actuator, a valve assembly that controls flow of fluid to the
hydraulic actuator, and a function controller which operates the valve assembly. Thefunction controllers exchange messages over a communication network which has a finitebandwidth. Access to the network is controlled by determining which function controllersgovern high priority operations and allowing those function controllers to send
messages as often as once every first interval of time. The other function controllers arelimited to sending messages no more often than once every second interval of time,which is longer than the first interval of time.
