Improved Robust Performance Design for Passive Uncertain Systems—Active Use of the Uncertainty Phase and Gain
TL;DR: A novel model for PR uncertainties which captures the frequency-dependent gain bound is proposed, and the corresponding design theory is established to actively utilize both gain and phase bounds of the uncertainty in the robust performance design.
Proceedings ArticleDOI
Economic operation of smart grid based on the statistics of renewable energy
TL;DR: In this paper, a new operation method for smart grid which assures both the power quality and the economy of the operation is proposed, and two peak-cut methods are proposed to improve the frequency performance when the frequency bound is not assured.
Journal ArticleDOI
Neo Robust Control Theory–Beyond The Small-Gain and Passivity Paradigms–
TL;DR: The modeling of uncertainty accounting for both gain and phase, robust stability conditions and their state space characterization is discussed.
