— In this paper we propose a fuzzy PI-PD controller that is tuned by using Genetic Algorithm(GA). The fuzzy PI-PD controller preserves the linear structure of the conventional one, but has self-tuned gains. The proportional, integral and derivative gains are nonlinear functions of their input signals having certain adaptive capability in set-point tracking(More)

Social bookmarking is one of the many phenomena in the Web2.0 environment. They are largely experimental, but some of them are very popular and very useful. Delicious is one of the most popular social bookmarking tools.The general internet users as well as the teachers and learners have been well adapting to the emerging technologies to integrate the(More)
This paper presents a Modified Smith Predictor (MSP) controller to design a novel Active Queue Management (AQM) scheme. The controller decouples the setpoint response from the load response and shows a stable response for a Transmission Control Protocol(TCP) flow dynamics, which is highly oscillatory or unstable under practical conditions. The proposed(More)
A simple closed loop identification method is proposed to design a PID-P controller for TITO systems. A pair of relays is simultaneously connected in parallel with the PID controllers. Based on the limit cycle data, a diagonal TITO transfer function model of the system dynamics are obtained. Then the PID parameters are estimated using the identified model(More)
