Speech Title:

A new theoretical framework of parameter estimation of linear systems


Abstract:

In this talk, a brand-new methodology to estimate unknown system parameters for a broad class of second-order linear systems by using the steady state sinusoidal output measurements is proposed. It is shown that, for parameter estimation, the input to a linear system can be chosen as the linear combination of a group of sinusoids. The amplitudes of the steady state sinusoidal output components can be extracted from the system output measurements. The unknown system parameters can then be estimated in the frequency domain with the amplitudes information of steady state sinusoidal output components. The advantages of this method are two folds: (i) Only the steady state output measurements in a fundamental period are required for determining the amplitudes of the steady state output sinusoidal components; (ii) The system parameters can then be estimated within the finite frequency band of the steady state output sinusoidal components. Most importantly, this new method provides a global optimization mechanism, within a fundamental period, to accurately estimate unknown system parameters in the frequency domain. A simulation example for second-order systems with the minimum phase and non-minimum phase, respectively, are implemented to show the effectiveness of the new parameter estimation methodology.
