摘要:AbstractIn this paper, a method of identification is introduced which is based on the so-called output over-sampling scheme. When analyzing the frequency domain properties of the over-sampling scheme, it is found that the error of the frequency response is pushed away from the frequency band of the plant. The method first identifies a high frequency model using low-pass filtering and then convert the model to the original sampling frequency. Simulations show that the model parameter variance can be made much smaller than the Cramer-Rao bound of the model identified from the data of the original sampling frequency.
