Să se proiecteze un regulator PID cu Amplificator operațional cu funcția de transfer H(s)=Kpc( 1+1/Ti(s)+Td(s)), unde Kpc=-10, Ti= 150 ms și Td=80. Plaja tensiunilor de reacție, ieșire și referință este +10V. Doresc schema electronică împreună cu calculele matematice folosite pentru determinarea valorilor fiecărui dispozitiv electronic folosit.

Aceasta aplicatie doresc ca atunci cand telefonul atinge un anumit procentaj de incarcare al bateriei(exemplu 100%) sa intrerupa alimentarea incarcatorului, iar cand acest procentaj scade sub un anumit nivel( exemplu 25%) sa reia incarcarea, adica la anumite procentaje ale bateriei sa inchida si sa deschida un circuit(releu). Conectarea aplicatiei sa poata fii facuta prin bluetooth. Va multumesc anticipat, iar pentru mai multe detalii nu ezitati sa ma contactati.
