On the contraction of excitable systems

open access: yesEuropean Journal of Control
We study the contraction of Hodgkin-Huxley model and its role in the reliability of spike timings. Without input, the model is contractive in the region of physiological interest. With impulsive synaptic inputs, contraction is retained provided that the input events are sparse enough. Contraction is lost when the input firing rate is too high.

Power Compatibility of Induction Motors in Industrial Grids Containing Synchronous Generators

open access: yesEnergies
Starting an induction motor causes voltage sag in the industrial grid that may disturb the operation of grid equipment. Direct-on-line starting is the simplest and most cost-effective method for starting induction motors, but also the most problematic ...

Research on flexible excitation system applied to improve transient stability characteristics of the receiving-end power grid

open access: yesZhejiang dianli, 2022
The transient forced excitation of the traditional excitation system used for synchronous condenser is limited and unmaintainable. A flexible excitation system can improve the crest value of transient forced excitation and maintain the forced excitation ...

Excited States of the Helium-Antihydrogen System [PDF]

open access: yesPhysical Review Letters, 2007
Potential energy curves for excited leptonic states of the helium-antihydrogen system are calculated within Ritz' variational approach. An explicitly correlated ansatz for the leptonic wave function is employed describing accurately the motion of the leptons (two electrons and positron) in the field of the helium nucleus and of the antiproton with ...

Tuning of Fractional Order PIλ Dμ Controllers using Evolutionary Optimization for PID Tuned Synchronous Generator Excitation System

open access: yes, 2018
This paper has propounded the notion of the design of cascaded integer order (IO) PID - fractional order (FO) PIλ Dμ controller by evolutionary multi-objective based optimization approach for a synchronous generator excitation system.

Control Systems with Almost Periodic Excitations [PDF]

open access: yesSIAM Journal on Control and Optimization, 2009
For control systems described by ordinary differential equations subject to almost periodic excitations the controllability properties depend on the specific excitation. Here these properties and, in particular, control sets and chain control sets are discussed for all excitations in the closure of all time shifts of a given almost periodic function ...
