Based on the Filter type selected in the block menu, the Second-Order Filter block implements the following transfer function: Low-pass filter: High-pass filter: Band-pass filter: Band-stop (notch) filter: The key characteristics of the Second-Order Filter block are: Input accepts a vectorized...
The feedback is taken before or after the filter inductor. The thing that is most surprising to people is how much the open-loop Bode plot changes even when the filter is not “in” the feedback loop. Since the control loop is affected with or without the filter in the feedbac...
Note that in order to reduce the numerical error, processes GP1–GP6 input and output signals were first filtered with a first-order low-pass filter with a time constant of 10 ms. Then, the parameters of Model (9) were calculated from the characteristic areas, according to the flowchart ...
