Abstract

A new identification procedure in discrete time systems is proposed. This method identifies the unknown parameters in the system by using the pulse response time history which is reconstructed through an ARMA model. With this identification, the excitation requirement on input is relaxed, and it results in easy installation. As this identification is done totally in time domain, it is applicable to the time variant systems. The sufficient conditions are obtained within which the identification is performed for such systems. A number of numerical simulations are conducted to confirm the availability. In the simulations, the simplified model of a launch vehicle in flight is treated to show the ability of the identification of the time variant system.
