Optimal linear and nonlinear control design for chaotic systems
(2005-12-01)
In this work, the linear and nonlinear feedback control techniques for chaotic systems were been considered. The optimal nonlinear control design problem has been resolved by using Dynamic Programming that reduced this ...
Nonlinear Dynamic Behavior, Deterministic Chaos and Nonlinear Control of a Micro Electro Mechanical Actuator System (MEMS)
(Destech Publications, Inc, 2015-01-01)
Micro Electro Mechanical Systems (MEMS) are systems composite by electrical and mechanical devices that interact by means of transducers elements, thus constituting one single and whole system. On the study of dynamic ...
Critical evaluation of FBD, pq and CPT current decompositions for four-wire circuits
(2009-12-01)
This paper investigates the major similarities and discrepancies of three important current decompositions proposed for the interpretation of unbalanced and/or non linear three-phase four-wire circuits. The considered ...
Harmonic propagation analysis in electric energy distribution systems
(2011-12-01)
An important alteration of the equivalent loads profile has been observed in the electrical energy distribution systems, for the last years. Such fact is due to the significant increment of the electronic processors of ...
Comparative analysis for reactive energy measurement methodologies, under non-sinusoidal conditions in three-phase four-wire circuits
(2011-12-28)
This paper presents some methodologies for reactive energy measurement, considering three modern power theories that are suitable for three-phase four-wire non-sinusoidal and unbalanced circuits. The theories were applied ...
Currents' physical components (CPC): Case studies in single phase systems
(2018-06-25)
This paper intends to apply in selected cases the Currents' Physical Components (CPC) Theory, developed by Czarnecki to interpret power properties through the decomposition of the system's currents into orthogonal components ...
Adaptation of Iterative Methods to Solve Fuzzy Mathematical Programming Problems
(World Acad Sci, Eng & Tech-waset, 2006-01-01)
Based on the fuzzy set theory this work develops two adaptations of iterative methods that solve mathematical programming problems with uncertainties in the objective function and in the set of constraints. The first one ...
A comparative analysis of FBD, PQ and CPT current decompositions - Part II: Three-phase four-wire systems
(2009-12-01)
This paper investigates the major similarities and discrepancies among three important current decompositions proposed for the interpretation of unbalanced and/or non linear three-phase four-wire power circuits. The ...
On the Marginal Deformations of General (0,2) Non-Linear Sigma-Models
(Amer Mathematical Soc, 2015-01-01)
In this note we explore the possible marginal deformations of general (0,2) non-linear sigma-models, which arise as descriptions of the weakly coupled (large radius) limits of four-dimensional N = 1 compactifications of ...
