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....

A review of uncertainty quantification techniques is provided for a variety situations involving uncertainties in model inputs (independent variables). The interest are divided into three categories: (i) when prediction quantified based on uncertain inputs, (ii) parameter estimate calculated by propagation from measured and outputs, (iii) corresponding estimates. For all situations, linearizati...

We use data from a small aperture array in southern California to quantify variations in source parameter estimates at closely spaced stations (distances ranging from ∼7 to 350 m) to provide constraints on parameter uncertainties. Many studies do not consider uncertainties in these estimates even though they can be significant and have important implications for studies of earthquake source phy...

In this paper Kharitonov's theorem for the robust stability'.df kterval , polynomials is proved using the second method of Lyapunov. The Hermi+' matfi is taken as the matrix of the form which is used as a Lyapunov funct i i tq prove B m i B stability. It is shorn that if the four Hermite matrices eorrespqndmg; to the four Xharitonov extreme pobmomials are positive definite, the Hermitemhtriw of...

In this paper Kharitonov's theorem for the robust stability of interval polynomials is proved using the second method of Lyapunov. The Hermite matrix is taken as the matrix of the quadratic form which is used as a Lyapunov function to prove Hurwitz stability. I t is shown that if the four Hermite matrices corresponding to the four Kharitonov extreme polynomials are positive definite, the Hermit...
