The proposed filter offers the 2nd order functions (HP, BS, AP) and it also offers HP
transfer function of the 1st order and direct transfer between the input and output of the filter.
Here, [X.sub.pn] is the ANN input, [W.sub.kn] the weight, [b.sub.k] the bias, and [f.sub.K] the
transfer function for the hidden layer.
We assume that the
transfer function of the regulator (3) retains its form for random variations of the parameters k, [a.sub.1], [a.sub.2], [a.sub.3], [b.sub.1], [b.sub.2].
System identification with a
transfer function involves determining the
transfer function between the input and output as well the noise.
[13] studied the accuracy of volume rendering for arterial stenosis measurement and the results suggested that the choice of
transfer function parameters greatly affects the accuracy of volume rendering, while accurate
transfer function parameters selection is still a challenge due to the lack of meaningful guidance information and intuitive user interface.
where: x(s) - n is vector of variable systems represented according to Laplace; A(s) - nxn uninterrupted
transfer function matrix; [x.sup.Ti] (s)--discrete transformation in times [T.sub.i], i = 1, ..., N vector x(s); R - n - standardized input vector which, according to system linearity, can be considered as vector R' = [1 0 0 ...
From the average
transfer function, the model parameters are obtained and the controller parameters are obtained based on Zeigler-Nichols tuning method[2] as given in the equations 4,5and 6.The control parameters are tabulated (Table 3).
In Table 2 the
transfer function coefficients identified for each pilot/test examined are presented (pseudointegrator poles, [p.sub.1] and [p.sub.2], are set equal to 1 Hz).
Furthermore, the nonlinear
transfer function does not obey the rule of superposition.
The
transfer function of the converter block is therefore given by the following equation [46]:
By applying the
transfer function, the value of the outputs would be determined.
The problem statement and solution rely on the concept of generalized
transfer function for nonlinear systems [8,26].
