Closed Loop Identification Based on Quantization
This paper proposes a new closed-loop identification scheme for a singleinput-single-output control loop. It is based upon a quantizer inserted into the feedback path. The quantizer can be used to generate an equivalent persistently exciting signal with which the well known two-stage and/or two-step method can be used directly. Simulation examples and an experimental demonstration are used to i...
متن کاملClosed-Loop Identification of Power System Based on Ambient Data
Small fluctuations caused by random changes of loads exist continuously in power grids, which are called ambient signals. Using time-synchronized phasor measurements, the closedloop identification of power system based on ambient data is discussed, which can reflect accurate operating conditions currently and provide critical information for system analyzing and controller designing. The closed...
متن کاملA virtual closed loop method for closed loop identification
Indirect methods for identification of linear plant models on the basis of closed-loop data are based on the use of (reconstructed) input signals that are uncorrelated with the noise. This generally requires exact (linear) controller knowledge. On the other hand, direct identification requires exact plant and noise modelling (system in the model set) in order to achieve accurate results, althou...
متن کاملCyclic Spectra Based Approach to Direct Closed-Loop Identification
The direct closed-loop identification algorithm in frequency domain is considered in this paper. It is shown that the input and output signals obtained through the over-sampling technique have cyclic spectra, which give the frequency transfer function of the over-sampled model. Then a cyclic spectra based identification algorithm is implemented in the frequency domain. It is clarified that the ...
متن کاملCyclic Spectral Based Approach to Closed-loop Identification
The direct closed-loop identification algorithm based on cyclic spectral is considered in frequency domain in this paper. It is illustrated that the input and output signals obtained through inter-sampling technique have cyclic spectral, and the cyclic spectral contain plant model information, then the plant model can be estimated just from the cyclic spectral of the plant input and output sign...
