The non-search method is a simple, reliable and universal method for calculating the settings of suboptimal controllers, including algorithms such as PD, PDD and PIDD.
However, given inthe software implementation of this method has a number of drawbacks, which makes it difficult to use in microprocessor control devices.
Among the shortcomings can be identified as:
Ambiguity in determining the range of operating frequencies, which, even if there is a smoothing link in the structure of the transfer function of the regulator, can lead to negative settings;
