CONGESTION CONTROL SYSTEM WITH PID CONTROLLER USING FUZZY ADAPTATION MECHANISM

摘要

The congestion control in computer network is a problem of controlling a specific object such as a computer network. The paper provides an adaptation mechanism designed to prevent unstable behavior of the system, with fuzzy rules, and with an inference mechanism that identifies the possible sources of nonlinear behavior. The adaptation mechanism can be designed to adjust PID controller tuning parameters when oscillatory behavior is detected. Tests in nonlinear and uncertainty process are performed.
