Abstract

The nonstationary systems parametric estimate requires the continuation of its parameters which vary abruptly at unknown random moments. These are the abrupt parametric variations which were considered in this work to be managed like ”faults”. The considered signals here are nonstationary and are characterized by time variable parameters. The estimate of these parameters requires the choice of an algorithm having the capacity to continue their evolution. The various hybrid adaptive estimate methods showed that these capacities can be reached by a compensation of a gain and its update in online. In this paper, a method of estimate is proposed, based on the fault detection. The general algorithm implemented gives place to several methods which will be detailed. Experimental tests of some methods on a second order autoregressive synthesis signal are carried out and then commented.
