| Abstract: | For reducing the bad effect on industrial ethernet network control system (IECS), which results from network delay time, and assuring the control requirements of IECS, the computing model of network delay time was built and its computing approach was presented on the base of load analysis and queue theory. By use of the network delay time and traditional PID controller design approach, GA (Genetic Algorithm) was proposed to implement PID tuning for meeting time-frequency requirements. In order to enlarge searching scopes and get more excellent individuals, by introducing crowding niche strategy to GA, the design approach of IECS based GA with the strategy was proposed. |
