It is usually difficult to build a real-time (RT) control network using the standard TCP/IP and Ethernet, because the medium access control (MAC) protocol of 10 BASE-T Ethernet, the 1-persistent carrier sense multiple access with collision detection (CSMA/CD) protocol, has unpredictable time delay characteristics. When RT packets are transported over an ordinary 10 BASE-T Ethernet, RT packets from a node may experience a large time delay. This may sometimes cause closed-loop instability and performance degradation. We propose a compensating scheme which consists of two compensators, i.e. a fuzzy-PID controller and a wavelet neural network compensator, to diminish the influence of time delays from instability while maintaining performance. The proposed design is experimentally verified to show its effectiveness and superiority.
