Abstract:
1. A method for prediction of a response of a parameter sensor (D 0 ) used for measuring a parameter of an external object; said parameter sensor (D said parameter sensor (D said calculator is characterized with: a time constant (T) characterized with limits of calculation accuracy (Ch); a predetermined time parameter called a dead zone, and characterizing a range of changing the time constant T, said dead zone has a predetermined minimal boundary (Tz a variable (Si) holding a time value passed from the beginning of calculation carried out by the calculator; a first time variable (Td a second time variable (Td a query time period (T said parameter sensor (D 0 ) is associated with a pre-programmed microprocessor herein called a second correction circuit (D 0 K) comprising two correction elements; and said parameter sensor (D 0 ) is associated with a pre-programmed microprocessor herein called a third correction circuit (P) comprising one correction element; said method comprising the steps of: determining a first derivative and a second derivative of said parameter; determining output signals of each said correction element of the first correction circuit (D setting up the cycle ‘for’ and assigning to the variable (Si) of a O-value thereby starting time counting carried out by the calculator; forming the first correction circuit (D determining output signals of each said element of the second correction circuit (D forming the second correction circuit (D forming the third correction circuit (P) connected with said parameter sensor (D determining a first derivative (DM) of an output signal of the third correction circuit (P); using said calculator, calculating the time constant (T) of the aperiodic element recording the time constant (T) calculated and assigning thereof to the first time variable (Td entering the first time variable (Td using said calculator, calculating a next value of said time constant (T) and assigning thereof to the second time variable (Td entering the second time variable (Td using said calculator, continuously calculating a current value of the time constant (T), while determining a condition of: calculating new values of the query time period (T based on the calculated value of said query time period (T continuously determining said limits of the calculation accuracy (Ch); continuously recording the current values of the power counter (n); entering the calculated current time variables (Td determining a time of termination of the cycle ‘for’; and determining a first derivative (DB
