Abstract :
This paper describes, from a deterministic view point, an online process monitoring method for small signal behavior of time invariant stable systems at a given operating point. The monitoring is accomplished by using an m-sequence modulated low-pass wavelet as the probing signal, and a cyclic reference signal as the correlator. This method allows one to achieve high resolution, high signal to noise ratio monitoring, and the acquired data can be used for online diagnosis
