This paper develops a Kalman filter-based method to estimate the magnitude and phases of currents and voltages of a single-phase transmission line. Unlike common-place practices, in which phasors are estimated by using Fourier-based or least squares

This letter presents a new algorithm for designing robust output-feedback controllers in the presence of structured uncertainty. The proposed approach is an alternative to the popular D-K Iterations, consisting of a pair of LMIs (Linear Matrix Inequa

This article reexamines the problem of estimating symmetrical sequence components, more specifically, the optimal estimation of the magnitude and phases of sequence components. We first address and compare different setups for the optimal Kalman filt

This paper presents a new approach to estimate transmission line parameters based on Phasor Measurement Units (PMUs) data. Such approach considers a new set of phasorial equations incorporating noise on the model and a solution based on the Minimum V
