—The use of distributed energy resources is increasingly being pursued as a supplement and an alternative to large conventional central power stations. The specification of a power-electronic interface is subject to requirements related not only to the renewable energy source itself but also to its effects on the power-system operation, especially where the(More)
In this paper, we present a new approach to evaluation of signal integrity that is based on signal energy density as a function of time and frequency, represented by its wavelet scalogram. Using signal integrity ratio and cumulative energy ratio, we illustrate signal integrity analysis with simulated examples, followed by the demonstration of their(More)
A new approach to adaptive model reference control, based on Lyapunov's direct method, is presented. A design procedure for single output systems has been developed and the results verified by computer simulation. The algorithm presented in this paper guarantees asymptotic stability, provided that the transfer function of the equivalent error system is(More)
Precision adaptive control has been accomplished using a neural network to generate the required system dynamics, given the desired input and output. That is, an artificial neural network has been designed and incorporated into an adaptive control system to function as a synthesizer of a dynamic plant which senses and continually reduces, in a learning(More)
