Sistema de auto sintonia para controlador PID aplicado a plantas térmicas
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Eletrotécnica, 2011-11-17)
This paper proposes a methodology of control system, applied to thermal plants, composed of two loops. In this context, studies were performed with a system of internal control loop, which always approximates the controlled ...
Estudo comparativo entre diferentes controladores PID baseados em técnicas de predição aplicados a processos com atraso de transporte
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de ElétricaEngenharia ElétricaUTFPR, 2019-06-12)
The dead-time is the time difference between the manifestation of the input signal and the output signal of the system, present in some industrial systems. Considering that PID controllers (Proportional, Integral and ...
Estudo e projeto de um conversor boost dois níveis
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de ElétricaEngenharia ElétricaUTFPR, 2015-11-17)
