Using serial bluetooth converters as a sensor link in networked control systems
(2011-12-01)
Networked control systems (NCS) are distributed control system in which sensors, actuators and controllers are physically separated and connected through communication networks. NCS represent the evolution of networked ...
Comparative analysis of current and voltage-controlled photovoltaic Maximum Power Point tracking
(2011-12-28)
Maximum Power Point tracking (MPPT) in photovoltaic (PV) systems may be achieved by controlling either the voltage or current of the PV device. There is no consensus in the technical literature about how is the best choice. ...
Lyapounov stability for impulsive dynamical systems
(2002-12-01)
This article addresses the problem of stability of impulsive control systems whose dynamics are given by measure driven differential inclusions. One important feature concerns the adopted solution which allows the consideration ...
A comparative study between two relaxed LMI-based fuzzy control designs
(2005-09-01)
A comparative study, with theoretical analysis and digital simulations, of two conditions based on LMI for the quadratic stability of nonlinear continuous-time dynamic systems, described by Takagi-Sugeno fuzzy models, are ...
Well-conditioned robust observer for detection of faulty systems components
(1997-12-01)
A new concept of fault detection and isolation using robust observation for systems with random noises is presented. The method selects the parameters from components that may fault during the process and constructs well ...
Virtual simulator for mobile robots navigation systems
(2008-10-13)
This paper presents the virtual environment implementation for project simulation and conception of supervision and control systems for mobile robots, that are capable to operate and adapting in different environments and ...
Multiloop controller and reference generator for a dynamic voltage restorer implementation
(2008-12-23)
This paper deals with the design and analysis of a Dynamic Voltage Restorer output voltage control. Such control is based on a multiloop strategy, with an inner current PID regulator and an outer P+Resonant voltage controller. ...
H2 and/or H∞-norm model reduction of uncertain discrete-time systems
(1999-12-01)
This paper addresses the problem of model reduction for uncertain discrete-time systems with convex bounded (polytope type) uncertainty. A reduced order precisely known model is obtained in such a way that the H2 and/or ...
Variable speed refrigeration system with HPF input rectifier stage
(2008-09-22)
This paper is based on the analysis and implementation of a new drive system applied to refrigeration systems, complying with the restrictions imposed by the IEC standards (Harmonic/Flicker/EMI-Electromagnetic Interference ...
Comparison of FACTS STATCOM models for damping oscillations in power system due to small perturbations
(2011-05-31)
This paper presents small-signal stability studies of a multimachine power system, considering Static Synchronous Compensators (STATCOM)and discussed control modes of the STATCOM. The Power Sensitivity Model(PSM)is used ...
