Abstract

A novel frequency domain closed-loop identification algorithm is proposed using the output inter-sampling scheme. It is illustrated that the inter-sampled plant output has cyclostationary property that can be used to eliminate the correlation between the plant input and output noise even though no persistently exciting test signal is available. It can be applied for the unstable plant identification problem, and can be extended to the situation where the output disturbance noise is colored. An experiment of magnetic suspension system is performed to demonstrate the effectiveness of the proposed approach.
