We propose one networked control strategy for linear SISO systems affected by variant communication delays. The purpose of this\r\napproach is to adjust, by using the fuzzy logic, the command provided by the PID controller. The input for the fuzzy logic controller\r\n(FLC) is represented by the delay and the variation of delay, and the output is used to adapt the PID controller�s command to the\r\nnew value of the communication delay which occurs in the network. Simulation and implementation results are presented. The\r\nresults show performance improvement when using our control strategy. The authors present the implementation for an axis of a\r\n3D crane, using the Ethernet/IP (TCP/IP) communication protocol.
