Improved Reduced-Order Model for PLL Instability Investigations

an improved mixed order model for describing thermoluminescence glow curves

an improved mixed order model is presented to describe the thermolumunescence (tl) glow peaks. in this model a fraction of charge carriers, which undergo nonradiative recombination following thermal excitation is taken into account. therefore, it is expected that the proposed model will produce more realistic kinetic parameters than that of mixed order model. the tl glow curves generated by the...

Reduced order model for doubly output induction generator in wind park using integral manifold theory

A dynamic reduced order model using integral manifold theory has been derived, which can be used to simulate the DOIG wind turbine using a double-winding representation of the generator rotor. The model is suitable for use in transient stability programs that can be used to investigate large power systems. The behavior of a wind farm and the network under various system disturbances was stu...

A Reduced Order Model for Epitaxial Growth

We formulate a reduced order model for multi-layer, epitaxial growth of a thin film. The model describes layer-by-layer growth using three bulk (i.e. scalar) quantities per layer: average coverage ψ, average island number density n and average adatom density ρ for each layer. The model relies on simplifying assumptions on the geometry of the islands, as well as several approximations for the ph...

Improved Reduced Order Modeling Strategies for Coupled and Parametric Systems

Reduced-order H∞ Controllers Based on Improved Genetic Algorithm

An approach of reduced-order H∞ controller for a class of linear continuous dynamic systems is presented based on Genetic Algorithm. Necessary and sufficient conditions are given, in terms of linear matrix inequality, for the existence of controller. A rank condition is changed to object function of genetic algorithm(GA). The minimum order nk of the controller and a corresponding parameter pair...
