Abstract

This paper considers the design of networked feedback controllers with more efficient allocation of network resources. With a given admissible controller, an L2-gain preserving event-triggered transmission policy is proposed for determining whether the currently measured state at the sensor node should be sent to the controller through the network for updating control signal. In this way, not all the measured data are sent and then the network traffic in a networked control system can be reduced. An algorithm is proposed to enlarge the transmission boundary of the event-triggered transmission rule for increasing inter-transmitting times. An illustrative example is given for verifying the benefit of the proposed approach.
