Validation of models in relation to the model use has shown that models should be evaluated not only in relation to the usually performed output error, but also in relation to the input error and optimal control signal.
NC and KT analyzed the data and performed output analysis.
A linear observer is designed and implemented to perform output-feedback control of the plant.
Blind source separation (BSS) based methods have been shown to be efficient and powerful to perform output-only modal identification.
Figure 4 Sequence diagram model with context-awareness information and process variables to ubiquitously perform output results.
Subspace identification algorithms have proven efficient for performing output-only modal analysis of mechanical systems subject to uncontrolled, unmeasured, and non-stationary excitation.
Alternately, in other works, to perform output feedback, the contact force is evaluated by means of load cells whose measurements are compensated by accelerometers [11], which could also be very expensive mainly for their quick deterioration during the runs of the train.
If TP multiplier performs N bit multiplication, then its output sum (S) bits are from S0 to S15 as demonstrated in Figure 3, and when N/2 bit multiplication is performed, the output sum bits are from S0 to S7 and S8 to S15, i.e., twin output is taken as illustrated in Figure 4 and N = 8 for the illustrated example.
The selected analysis options are performed, and output is written to disk in files.
This analysis can be performed using output from fitting standard weighted linear regression models, whilst ensuring that the reported standard errors are adjusted, as explained by Sharp and Thompson [ 2].
Owing to the different sampling rates of the measurement sensors, the model update is performed using different outputs, or combinations of outputs, at each update time.
