摘要
Fuzzy logic rules are applied to a method for indirectly measuring a physical signal to be monitored which would be difficult to directly measure. The measuring method comprises the steps of obtaining a derived physical signal from the physical signal to be monitored and measuring a value of the derived physical signal and its variations over time at suitably selected check points. A first set of fuzzy logic rules are applied to ascertain the presence or absence of an index signal adapted to mark at least first, second and third operational zones of the derived physical signal. Only the second operational zone is characterized by the presence of the index signal. First and second significant values of the physical signal to be monitored are measured as start and end values, respectively, of the second operational zone. An apparatus for indirectly measuring a physical signal is also disclosed.
