Abstract:

A servo system is described which makes it possible to determine predict the limit toward which some physical process tends, long before the process terminates. For example, using a thermocouple, the drop in temperature of molten metal can be measured long before the metal has been completely heated. The system contains a transducer for the linear conversion of changes in the investigated physical process into changes of electric voltage. The limit asymptote to which the investigated physical process tends is determined predicted before the process terminates by using an electronic analog of the function which is the quotient which results when the time-dependence of the investigated process is divided by the equation of the asymptote. The voltage at the analog input, one of the system parameters, is maintained such that the voltage at the analog output equals on the selected scale the voltage at the transducer output. The analog is controlled with a control unit which changes some parameter of the analog the second parameter of the system until it corresponds to the investigated physical process. Author
