Abstract:The simulator of power part of electric drive is under consideration in the paper. It is based on the software and hardware of National Instruments Company and includes model of converter and motor. The simulator is designed to setting up the electric drive and to explore the modes of its operation.
“…It can be implemented on microcontroller or FPGA. The solution with FPGA is closer to the reality [5,6]. The software project for power converter or FPGA has no significant differences but in this case we need a separate FPGA device.…”
This paper considers the model of different types of electric drives which is designed as a project for Code Composer Studio for TMS320F28xx microcontrollers and is used in Motor Control course for coursework. The review of different solutions for motor control education course is given and the demands to the model are stated. The description of the model is given and the sample of the control system with experimental results is shown. The link to the project for Code Composer Studio and its description is given.

“…Desta forma, o tempo envolvido na aquisição dos dados, com o potencial de abranger todas as configurações possíveis dos tratamentos de infusoterapia, dificultam a realização de pesquisas na área. Assim, uma das formas de evitar esse inconveniente é a exploração de simuladores de software-hardware [Ziuzev et al 2014].…”
Infusion procedures are among the most common in hospitals and have a high volume of adverse events in their operation. This paper presents a simulator, called SPODi, that allows an agile construction of the operational profiles of intravenous devices, enabling them to be evaluated when adverse events occur during the period of use. SPODi simulator was validated with real data extracted from a physical prototype (SPODi _Med) which was specifically build with this function. The results obtained, considering a 95% confidence interval when applying the t Student statistical test, indicate that SPODi can be used to infer the behavior of real infusion equipment.Resumo. Os procedimentos de infusão estão entre os mais usuais em hospitais e apresentam um volume elevado de eventos adversos na sua operação. Este artigo apresenta um simulador, denominado SPODi, que permite uma construção ágil dos perfis operacionais de dispositivos intravenosos, possibilitando que os mesmos possam ser avaliados quando da ocorrência de eventos adversos durante o período de seu uso. O simulador SPODi foi validado com dados reais extraídos de um protótipo físico (SPODi_Med) construído especificamente para essa finalidade. Os resultados obtidos, considerando um intervalo de confiança de 95 % quando da aplicação do teste estatístico t Student, apontam que o SPODi pode ser empregado para inferir o comportamento de um equipamento real de infusão.
IntroduçãoOs dispositivos médicos modernos, com a intenção de qualificar o esforço de gerência por parte dos profissionais da saúde, muitas vezes exploram operações autônomas nos diferentes procedimentos que realizam [Dey et al. 2018]. Entre os procedimentos clínicos mais rotineiros em hospitais, estão os tratamentos que empregam os sistemas intravenosos. Cerca de 80% dos pacientes hospitalizados carecem de recursos terapêuticos intravenosos [Cheng et al. 2016]. A entrega de medicamento intravenosa é prescrita considerando as ações das diferentes concentrações da absorção do medicamento na corrente sanguínea ao longo do tempo para diferentes métodos de entrega.Os equipamentos de infusoterapia são utilizados em situações que exigem diferentes decisões por parte dos profissionais de saúde, as quais geram impactos diversos no tratamento do paciente. Assim, uma forma de contribuir para as decisões médicas consiste
“…A large number of authors of articles [1,2] and conference papers [3][4][5][6][7] are interested in this subject as well. Due to the development of software and hardware, it is possible to make a complex modelling of electric drive systems in real time at low operational cycle (about 1 s) by receiving digital signals, processing and sending analog signals.…”
Simulator of electric drive system based on power converter with control system which realizes in real time model of converter, motor and mechanism is discussed. Power simulator is intended for converters testing and for their operating modes studying. Simulator repeats electric drive instantaneous current and angular velocity.
