PID controller is widely used in different kinds of industry circumstance. Because of the difficulty for modeling the industry plants and the frequent change of the parameters of plants, it often could not be gotten optimal control effects by using common PID controllers. So it is significant to find the tuning methods which are simple, practical and have good performance. A fuzzy tuning algorithm...
In rate-based flow control scheme, the important problem is to how to determine congestion occurrence and relief. The common methods is to set explicit feedback congestion indication (EFCI) bit in data header or nonincrease NI and congestion indication (CI) bits in RM cells to fulfil the task. Howerver, many studies have reported that the algorithm often cause the buffer occupancy oscillation due...
