Esta tese de dissertação tem como principal objetivo a implementação de controladores
fracionários utilizando diapositivos analógicos FPAA (Field Programable Analog Array).
Embora estes dispositivos já não sejam um tecnologia recente, não tiveram grande aceitação
comercial, daí não ter sido grande a sua evolução nesta última década. Mas para a elaboração de
alguns circuitos analógicos, nomeadamente filtros, amplificadores e mesmo controladores PID
(Proporcional-Integrativo-Derivativo) analógicos torna-se numa ferramenta que pode facilitar o
projeto e implementação.
Para a realização deste estudo, utilizou-se a placa de desenvolvimento da Anadigm
AN231K04-DVLP3 juntamente com o software disponibilizado pela mesma empresa, o
AnadigmDesigner2. Para a simulação e observação dos resultados foi utilizada a DAQ (Data
Acquisition) Hilink da Zelton juntamente com o software Matlab.
De forma a testar a implementação dos controladores fracionários nas FPAA foram realizados
alguns circuitos no software e enviados para a FPAA comparando os resultados obtidos na
simulação com os visualizados no osciloscópio. Por último foi projetado um controlador PIlDm
recorrendo aos métodos de aproximação inteira descritos neste documento implementados na
FPAA recorrendo ao uso de filtros de primeira e segunda ordem.
This dissertation has as a main goal the implementation of fractional controllers by using FPAA analogical devices. Although these devices are not a recent technology, they did not have great commercial acceptance yet, and their evolution during this decade has not been significant. However, in the creation of some analogical circuits, namely filters, amplifiers and even PID analogical controllers, it becomes a tool that can facilitate its design and implementation. For the realization of the study, it was used the development board AN231K04-DVLP3 together with the software provided by the same company, the AnadigmDesigner2. We used also the DAQ Hilink from Zelton together with the software Matlab for the simulation and results. In order to test the implementation of the fractional controllers in the FPAA we have created some circuits in the software and sent them to the FPAA while comparing the results from the simulation with the ones displayed in the oscilloscope. Lastly, we have designed a PIlDm controller by using the approach methods described in this document and implemented in the FPAA using first and second order filters.
