In this talk, a brand-new methodology to estimate unknown system parameters for a broad class of second-order linear systems with non-minimum phase is proposed by using the steady-state sinusoidal output measurements. It is shown that the input to a linear system is the linear combination of a group of sinusoids, the amplitudes of the steady state sinusoidal outputs are extracted from the system output measurements. The unknown system parameters can then be estimated in the frequency domain. The advantages of this method are two folds: (i) Only the steady-state output measurements in a fundamental period are required; (ii) The system parameters can be estimated within the finite frequency band of the steady-state output sinusoids.
