METHOD FOR DETERMINING A MEASUREMENT VARIABLE

摘要

The invention relates to a method for determining a measurement variable (Q), characterized by the following steps: providing a model (M) of a circuit (DAC) having at least one parameter (tau, Imax); actuating the circuit (DAC) by way of a preset signal (H), and detecting values (l1, l2,l3) of a manipulated variable (I) generated by the circuit in n discrete points in time (t1, t2, t3), and determining a value (tauDAC, lmaxDAC) of the at least one Parameter (tau, lmax) on the basis of the detected values (I1, l2, l3) of the manipulated variable (I) generated by the circuit (DAC); detecting values (J1, J2) of a variable (J) influenced by the circuit (DAC) in m discrete points in time (T1, T2), and determining the measurement variable (Q) from the measurement values (J1, J2) of the variable (J) influenced by the circuit (DAC), taking into account the model (M) of the circuit (DAC).
