摘要：The invention relates to a device for control of a quantity x, by acting on acontrol quantity y with which the quantity x is in a one-to-one relationship when the valueof a parameter h to which the quantity x is sensitive remains constant, the quantity x itselfbeing, for each of the controlled values xp, a one-to-one function of the parameter h, theparameter h being capable of varying in an interval including a reference value hi, and foreach of the values xp it is known to define a function yp = gp(h), yp being the value to begiven to the quantity y to obtain the value xp when the parameter has the value h, thevarious functions gp(h) having the property that the value of a second function gp, (h)may be deduced from the value of a first function gp(h) for the same value of the

parameter h by addition of a term known as a function of the difference between the realmeasured value hr of the parameter h and the reference value hi, the device beingcharacterised in that the quantity x is represented by the output magnitude of anoperational amplifier (10) having two inputs, a first (11) and a second (12) and in that tothe first input (11) is applied, by means of a control 200, a voltage Ui representative ofthe control quantity yi to be applied in order to obtain the output quantity of value xiwhen h has the value hi, to the second input (12) a voltage Vc is applied which is the

output quantity corrected by a correction device (40) of a sensor (30) of the parameter h,the output of the sensor (30) being corrected by the device (40) so that the correctedvoltage Vc is equal to zero when h = hi and, in the opposite case equal to H(hr - hi).
