A Comparative Study Above Two Self-Tuning Controllers With Aplication To The Control Of Synchronous Generator Excitation System
("Dunarea de Jos" University of Galati, 2000)This paper presents two self-tuning control structures synthesized through the minimization of two criterion functions. It is described the computation methodology of the control laws, both being particularized for the ... -
Limitations of a Static VAr Compensator (SVC) with Switched Capacitor Operating as an Active Filter
("Dunarea de Jos" University of Galati, 2001)The goal of this paper is to analyze the limitations of a static VAr compensator (SVC) with switched capacitor, when this operate as an active filter. The limitations considered and studied by simulation are in the zone ... -
On a Takagi-Sugeno Fuzzy Controller with Non-Homogenous Dynamics
("Dunarea de Jos" University of Galati, 2001)The paper proposes a Takagi-Sugeno fuzzy controller with non-homogenous controller dynamics with respect to the two input channels, that means, in the linear case, different transfer functions with respect to the reference ... -
Algorithms for Wireless Channel Equalization with Joint Coding and Soft Decizion Feedback
("Dunarea de Jos" University of Galati, 2001)The paper proposes a new approach based on Joint Entropy Maximisation (JEM) using a soft decision feedback equalizer (S-DE) to suppress error propagation. In its first section, the paper presents the principle of the ... -
Neural Network Schemes in Cartesian Space Control of Robot Manipulators
("Dunarea de Jos" University of Galati, 2001)In this paper we are studying the Cartesian space robot manipulator control problem by using Neural Networks (NN). Although NN compensation for model uncertainties has been traditionally carried out by modifying the joint ... -
Modelling Non-Stationary Wind Speed for Renewablwe Energy Systems Control
("Dunarea de Jos" University of Galati, 2001)This paper deals with the modelling of the wind speed, treated as a nonstationary process. In the proposed modelling methods, the wind speed has two components: a long and medium term-component, described by an available ... -
Robust Control Methods for a Recycle Bioreactor
("Dunarea de Jos" University of Galati, 2001)The paper presents a robust control design strategy for bioprocesses, which are characterized by strongly nonlinear dynamics. More precisely, we present the H2 methodology in order to compute the controller for a recycle ... -
Stability criteria for cellular neural networks
("Dunarea de Jos" University of Galati, 2001)A cellular neural network is an artificial neural network which features a multidimensional array of neurons and local interconnections among the cells. Neural networks are systems with several equilibrium states. It is ... -
Analysis of a Neuro-Fuzzy Approach of Air Pollution: Building a Case Study
('Dunarea de Jos" University of Galati, 2001)This work illustrates the necessity of an Artificial Intelligence (AI)-based approach of air quality in urban and industrial areas. Some related results of Artificial Neural Networks (ANNs) and Fuzzy Logic (FL) for ... -
Modeling of the Biodegradation in Multiphase Stirred Tank Reactor
("Dunarea de Jos" University of Galati, 2001)The surface response methodology is used to verify predicted models and to adapt them on particular conditions of growth. The effect of solvent addition during the linear cell growth on the enhancement of biodegradation ... -
On Activity Modelling in Process Modelling
("Dunarea de Jos" University of Galati, 2001)The paper is looking to the dynamic feature of the meta-models of the process modelling process, the time. Some principles are considered and discussed as main dimensions of any modelling activity: the compatibility of ... -
Comments on Clock Models in Hybrid Automata and Hybrid Control Systems
("Dunarea de Jos" University of Galati, 2001)Hybrid systems have received a lot of attention in the past decade and a number of different models have been proposed in order to establish mathematical framework that is able to handle both continuous and discrete ... -
Integrating Hypermedia Objects in an Tutoring System
("Dunarea de Jos" University of Galati, 2001)The paper describes the internal architecture of an Intelligent Tutoring System, CSTutor. The architectural design of the tutorial system was developed in a collaborative work at the Department of Computer Science of the ... -
On Exponential and Asymptotic Estimation of State Variables in Bioprocesses
("Dunarea de Jos" University of Galati, 2001)The paper presents on-line estimation strategies for bioprocesses, which are characterized by strongly nonlinear dynamics. A general form for the state observers is analysed and the exponential observability of bioprocesses ... -
Supervisory Control Technique for an Assembly Workstation as a Dynamic Discrete Event System
