On relaxed LMI-based designs for fuzzy regulators and fuzzy observers
(Institute of Electrical and Electronics Engineers (IEEE), 2003-10-01)
Relaxed conditions for stability of nonlinear, continuous and discrete-time systems given by fuzzy models are presented. A theoretical analysis shows that the proposed methods provide better or at least the same results ...
Comments on Magnetically levitated micro PM motors by two types of active magnetic bearings
(Institute of Electrical and Electronics Engineers (IEEE), 2002-03-01)
This note clarifies the design of proportional derivative (PD) controllers for the magnetic levitation systems of micro PM motors proposed in the above paper. It is shown that the PD controllers cannot stabilize the described ...
Real power losses reduction and loading margin improvement via continuation method
(Institute of Electrical and Electronics Engineers (IEEE), 2004-08-01)
This letter presents an alternative approach for reducing the total real power losses by using a continuation method. Results for two simple test systems and for the IEEE 57-bus system show that this procedure results in ...
Migration-driven diversity of super-Earth compositions
(2018-01-01)
A leading model for the origin of super-Earths proposes that planetary embryos migrate inward and pile up on close-in orbits. As large embryos are thought to preferentially form beyond the snowline, this naively predicts ...
Scheduling in a random environment: stability and asymptotic optimality
(Institute Of Electrical And Electronics Engineers, 2013-02)
We investigate the scheduling of a common resource between several concurrent users when the feasible transmission rate of each user varies randomly over time. Time is slotted and users arrive and depart upon service ...
Microgrid stability definitions, analysis, and examples
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
This document is a summary of a report prepared by the IEEE PES Task Force (TF) on Microgrid Stability Definitions, Analysis, and Modeling, IEEE Power and Energy Society, Piscataway, NJ, USA, Tech. Rep. PES-TR66, Apr. 2018, ...
Compositional modulation and surface stability in InGaP films: Understanding and controlling surface properties
(2007-04-08)
We investigate the formation of compositional modulation and atomic ordering in InGaP films. Such bulk properties - as well as surface morphologies - present a strong dependence on growth parameters, mainly the V/III ratio. ...
