2 May 2016 | | Abstract: | The problem of estimating parameters of linear control valve with hysteresis
is considered. The hysteretic behavior of control valve is formulated as a
switched linear model. An indicator vector, which shows the switching epochs of
switched linear model, is explored by subspace decomposition on measurements.
With the help of indicator vector, the noisy measurements are classified into
separate groups, each corresponding to up-stroke and down-stroke of control
valve respectively. The least squares technique is adopted to estimate the
parameters of control valve. It is shown that the proposed technique exactly
estimates the parameters and switching epochs in absence of noise and exhibits
dominant advantage in noisy case. | | Source: | arXiv, 1605.0347 | | Services: | Forum | Review | PDF | Favorites | |
