Method of regulating the temperature of an element cooled by a cryorefrigerator with periodic operation

摘要

The invention relates to a method of regulating the temperature of an element cooled by a cryorefrigerator with periodic operation, characterized in that it comprises the following steps: (a) measuring at least the periodic temporal evolution of the temperature T of the element, this evolution making it possible to obtain a temperature signal representative of the periodic operation of the cryorefrigerator; (b) constructing a periodic so-called equivalent thermal flux signal (Soeq), as a function of the temperature signal obtained in step (a); (c) constructing a thermal flux control signal, depending on the equivalent thermal flux signal constructed in step (b), said thermal flux control signal serving also, in return, for the construction of the equivalent thermal flux signal (ScDeq, S*oeq) during step (b); (d) injecting a thermal flux into the element, on the basis of the thermal flux signal constructed in step (c), so as to compensate for the measured periodic variations of the temperature T of the element.

1. A method of regulating the temperature of an element (10) cooled by a cryorefrigerator (2) with periodic operation, the method being characterized in that it comprises the following steps:
a) measuring at least the periodic time variation of the temperature T of the element (10), this variation serving to obtain a temperature signal representative of the periodic operation of the cryorefrigerator (2); b) constructing an “equivalent” periodic heat flux signal (Sφeq, S*φeq) as a function of the temperature signal obtained in step a); c) constructing a heat flux control signal (SW) depending on the equivalent heat flux signal constructed in step b), said heat flux control signal (SW) also serving, by return, in the construction of the equivalent heat flux signal (Sφeq, S*φeq) during step b); and d) injecting a heat flux (W) into the element (10) on the basis of the heat flux signal (SW) constructed in step c), in order to compensate for the measured periodic variations in the temperature T of the element.
