The improved method for reconstruction of measurands

The improvement of known, classic way of reconstruction of measurand has been presented. The measuring system output signal is followed by classic feedback system containing “associated model” of measuring system which is represented with structure defined by state variable scheme. If error of follow-up action is small, then output of associated model and its accessible derivatives can be used to reconstruction of measuring system input (measurand). Due to virtual operation of slowing down of measuring system output and multi-option possibility of choice of associated model one can substantially improve the accuracy of follow-up action and measurand recovery. The concepts of implementation of method for both types of system and signal representations, i.e. continuous-time and discrete-time, are presented in the paper. The examples confirming advantageous properties of proposed algorithm are attached.
