Abstract :
This work describes the adaptation of Dynamic Time Warping algorithm in order to be used on-line for residual computation purpose. The main motivation is to compensate modelling errors and hybrid systems behaviour with on/off sensors. To illustrate the proposed method a laboratory plant where significant time distortions are manifested has been used to test this approach.
