چکیده
Thas paper presents the desagn of a fuzzy usage parameter controller (FUPC) for ATM (asynchronous transfer mode) networks The usage parameter control (UPC) as here based on a dual leaky bucket (DLB) mechanasm, wath parameters of token generatzon rate and token pool saze. In FUPC, we further e m p l o y parameters of token-change rate and anterarnval tame of zncomzng cells as znput languastac varaables to reflect the usage satuataon an advance. Samulataon results reveal that the proposed FUPC possesses shorter response tame to detect vzolataon cells, keeps the output rate of the user close to the declared usage parameters, and thus achzeves more precase control than DLB.

Fuzzy Traffic Control of ATM Networks
In this paper, we will use the benefits of fuzzy logic to design a high performance traffic controller of Asynchronous Transfer Mode (ATM). In the proposed fuzzy traffic controller, the actual mean cell rate of traffic source is estimated and the traffic controller is adjusted so its loss load is equal to generated excessive load. In order to improve the channel utilization, the proposed contro...
متن کاملRobust Fuzzy Gain-Scheduled Control of the 3-Phase IPMSM
This article presents a fuzzy robust Mixed - Sensitivity Gain - Scheduled H controller based on the Loop -Shaping methodology for a class of MIMO uncertain nonlinear Time - Varying systems. In order to design this controller, the nonlinear parameter - dependent plant is first modeled as a set of linear subsystems by Takagi and Sugeno’s (T - S) fuzzy approach. Both Loop - Shaping methodology and...
متن کاملA New Fuzzy Stabilizer Based on Online Learning Algorithm for Damping of Low-Frequency Oscillations
A multi objective Honey Bee Mating Optimization (HBMO) designed by online learning mechanism is proposed in this paper to optimize the double Fuzzy-Lead-Lag (FLL) stabilizer parameters in order to improve low-frequency oscillations in a multi machine power system. The proposed double FLL stabilizer consists of a low pass filter and two fuzzy logic controllers whose parameters can be set by the ...
متن کاملOptimized Fuzzy Controller Design in Unbalanced Voltage Drop Mode for Dynamic Voltage Restorer
The loss of balanced voltages involves a voltage drop due to symmetric three-phase errors, or the initiation of high-power three-phase loads or symmetric three-phase switches. While these events in an unbalanced way lead to asymmetric voltage drops. Voltage drops can cause asymmetric load on the power grid, the occurrence of volatility, and even network power outage. One of the most common ways...
متن کاملFuzzy Congestion Control and Policing in ATM Networks
In this paper, usage parameter control (UPC) is presented to ensure that each source conforms to its negotiated parameters in ATM networks. To meet the requirements for the policing function, a fuzzy logic-based system is proposed to deal with the congestion control and policing problem in ATM networks. There are four types of different mechanisms, Jump Window (JW), Exponentially Weighted Movin...
