This paper considers a distributed PI-controller for networked dynamical systems. Sufficient conditions for when the controller is able to stabilize a general linear system and eliminate static control errors are presented. The proposed controller is applied to frequency control of power transmission systems. Sufficient stability criteria are derived, and it is shown that the controller parameters...
Regulating frequency deviation is one of the most important issues in power systems. For this purpose, it is necessary to maintain the balance between demand and supply power in real time. Governors change inputs of turbines when frequency variation is caused by a load change. But, in an overload condition, the governor cannot control the frequency drop because of its slow response. In this paper,...
In this paper, the novel approach to design the power system stabilizer using artificial neural network based Non Linear Auto Regressive Moving Average-L2 (NARMA-L2) controller has been presented. The controller has been used to generate the appropriate supplementary control signal for the excitation system of synchronous generator. The signal generated has been used to damp the low frequency oscillations...
Standard H∞ loop shaping design has two drawbacks. The first is that it is difficult to select appropriate loop shaping weights, and the second is that the resulting controller is very complex. To resolve the two drawbacks, a low order structured robust controller design scheme is proposed. The scheme is based on fixed structure weight optimization and static H∞ loop shaping controller synthesis....
A delay-locked loop of multi-band selector with wide-locking range and low power dissipation is presented. The architecture of the proposed delay-locked loop consists of phase frequency detector, charge pump, band selector, multi-control delay line, and start-up circuit. The multi-band selector is used to extend operation frequency of delay-locked loop by switching the multi-control delay line. The...
