Abstract

La presente invenzione si riferisce ad un metodo per controllare la temperatura di un sistema secondo una desiderata curva di temperatura che è divisa in predeterminati intervalli di tempo ed ha una desiderata temperatura assegnata a ciascun intervallo di tempo, il sistema essendo riscaldato mediante potenza riscaldante applicata ad un dispositivo riscaldante. E' lo scopo della presente invenzione quello di controllare la temperatura del sistema in modo tale che venga osservata la predeterminata curca di temperatura il più esattamente possibile. Questo scopo viene ottenuto secondo l'invenzione con un metodo di controllo della temperatura che è caratterizzato dal fatto che la potenza riscaldante da applicare al dispositivo riscaldante durante un intervallo di tempo è determinata in risposta alla temperatura desiderata e alla velocità di riscaldamento del corrispondente intervallo di tempo utilizzando caratteristiche di riscaldamento e di raffreddamento dinamico determinante empiricamente tipiche del sistema, dal fatto che la potenza riscaldante determinata per ciascun intervallo di tempo è convertita secondo una curva di taratura in un valore fissato per un dispositivo di controllo di tensione, dal fatto che la potenza riscaldante in realtà applicata al dispositivo riscaldante è determinata entro ciascun intervallo di tempo, detta potenza riscaldante avendo assegnata ad essa un valore fissato di confronto mediante la curva di taratura, e dal fatto che quando il valore fissato devia dal valore fissato in confronto di più di un valore predeterminato e fissato di tolleranza entro il corrispondente intervallo di tempo, il valore fissato del corrispondente intervallo di tempo successivo viene variato in risposta a detta deviazione.(Figura 2).
