Explicit Rate Controller Design Based on Smith Predictor in ATM Networks

In this paper, queue length in the buffer is regarded as a scale to evaluate quality of service. A dual Smith predictor is designed for flow control in a single bottleneck linked ATM network to guarantee the stability of the system with unmatched information in the model. It is shown that in the complex and dynamic environment, the dynamic performance of the network can be greatly improved by setting appropriate parameters, feedback filter and assistant inner feedback mechanism. A number of simulations are done to verify the theoretical analysis
