Justificativa e Objetivos Vários trabalhos têm abordado as citocinas que podem ser estimuladas e liberadas por lesão cirúrgica, trauma, infecção, inflamação e câncer. Níveis elevados circulantes das citocinas parece ter implicações no aparecimento de complicações e retardo da recuperação pós-operatória de pacientes. O objetivo da presente revisão é resumir(More)
First-Order plus Time-Delay (FOPTD) models are extensively used to approximate systems in order to tune PID controllers. Several step and pulse response based identification and relay based identification techniques have been developed. A time domain technique using a set of frequency domain information is proposed in order to recover a model which matches(More)
A design method based on the Diophan-tine equation is used for determining current controller parameters. The two main control objectives are: to put the closed loop poles in predefined locations;and to track the reference signal. The reference signal tracking problem is solved using the internal model principle. It introduces the reference generating(More)
