摘要：
A new method is used to derive the relationship between the open-loop-system Markov parameters and the closed-loop frequency response function for a linear stochastic system. The method is an extension of an existing time-domain closed-loop identification method to the frequency domain and is applied to the identification of a linear state-space model of a plant from closed-loop frequency response data with known feedback dynamics. Computer simulations of a highly unstable large-gap magnetic suspension system are found to agree with experimental results.
