Aim of this paper is to present a radio communication system that can be easily integrated in an emergency communication network, which is able to relay analog and digital data. Implementation of a multiprocessor radio network controller, based on the FPGA technology, is the main goal of this project. This configuration allows a multiple possibilities of communication: APRS data transmission and analogue...
This paper presents an innovative implementation of a radio communication system, which is able to transmit analog and digital data. The main goal of this project is to implement a multiprocessor system, based on the FPGA technology, which can control multiple radio transceivers. In this configuration allow a various possibilities of communication: analogue (voice) communication and data transmission...
The project aims the implementation of an hydro-wind hybrid system. The advantages of this are clear: to supply the electricity in the isolated houses or group houses with limited power consumption, an alternative to the connection at the National Power Grid, especially where this is not possible. The proposed hybrid model includes a physical wind subsystem that links physical model hydro subsystem...
This paper presents a solution, based on genetic algorithm, to the problem of automatic generation of timetable of scale work for companies considering various criteria such as those observed in the availability and suitability of resources, labor law, employees personal preferences and distribution of labor demand over period. Were used as references to the needs of a call center company that needs...
This paper presents the results obtained in the implementation of feed-forward artificial neural networks (FF-ANN) with one or several layers, used in the development of smart devices that needs learning capability and adaptive behavior. The networks were implemented using ANN specific blocks created by the authors using the system generator software. The training and the testing of the networks was...
The current paper is meant to display a development procedure for a Simulink/Matlab library with parameterized components which can be implemented in FPGA circuits. The usage of the library components shall ease and shorten the time for design and hardware implementation of a loop control for direct current motors. The system generator toolbox is to be used as a work environment in designing the parameterized...
In this paper authors propose a rapid and new method to design and optimize the electric motor control using field programmable gate array (FPGA). The elaborated designing algorithm takes advantage of the unification of ISE Xilinx digital designing environment with Matlab/Simulink simulation and testing environment, through system generator toolbox. This results in a faster and efficient design flow...
This paper is dedicated to the stability analysis of switched systems with uncertain switching signal. We consider the case of discrete time switched systems that are stabilized by a switched state feedback for which the switching signal may be temporary uncertain. Dwell time conditions for stability analysis of such systems are given. The approach is applied to the case of switched systems with time-varying...
This paper is dedicated to the stabilizability of discrete uncertain systems with exponential uncertainties. Such uncertain system are encountered in many application domains that use sampled-data controllers and communication networks. For the sake of generality, the design problem is presented in the context of switched systems. LMI robust control synthesis based on an equivalent polytopic model...
