Delay Based Robust H∞ Control Algorithm for TCP Networks Congestion Control to Disturbance Attenuation

Delay Based Robust H∞ Control Algorithm for TCP Networks Congestion Control to Disturbance Attenuation

Many real-time applications use Internet as a media to transmit their data and need guarantee for correct data transmission and limited transmission delay. It requires efficient network traffic protocols to avoid or limit the level of congestion. In this paper we propose, design and analyze a Robust Delay Based Controller (RDBC) for traffic management on transmission control protocol (TCP). Thi...

Delay Dependent H∞ Based Robust Control Strategy for Unified Power Quality Conditioner in a Microgrid

This paper proposes a novel robust control scheme based on delay-dependent H∞for unified power quality conditioner (UPQC) in a microgrid under the influence of the delay and parameter uncertainties. A new UPQC model considering the effects of the delay and parameter uncertainties is established. Then, the H∞ controller is designed based on the cone complementarity linearization (CCL) algorithm....

Revisiting TCP Congestion Control Using Delay Gradients

Traditional loss-based TCP congestion control (CC) tends to induce high queuing delays and perform badly across paths containing links that exhibit packet losses unrelated to congestion. Delay-based TCP CC algorithms infer congestion from delay measurements and tend to keep queue lengths low. To date most delay-based CC algorithms do not coexist well with loss-based TCP, and require knowledge o...

H∞ based Disturbance Attenuation for Iterative Learning Control

Previous research has shown that repetitive processes, a class of 2D systems, can be used to design linear model based iterative learning control laws for convergence and transient performance, with supporting experimental benchmarking. In many applications attenuation of disturbances acting on the plant signals will also be required. The new results in this paper are control law design algorit...
