What Does Fuzzy Logic Controller Mean?

Fuzzy logic controllers are similar to other control systems in that the controller is programmed to use data sets to accomplish a particular job. Where the fuzzy logic controller differs is in its use of fuzzy sets and its programming, which is in common words, rather than a more esoteric computer language, such as C++.

The combination of programming plus fuzzy sets allows the fuzzy logic controller to apply options offered by common sense and rule-of-thumb and other forms of experiential knowledge to automated practice.


Trenchlesspedia Explains Fuzzy Logic Controller

Fuzzy logic controllers, a long-time control staple in manufacturing, and the world of trenchless technology began to come together in the mid-1990s when these controllers were used to maintain the drill's path and such elements as drill speed, automatic mud logging and steering.

The fuzzy logic controller's "touchy-feely" system effectively mimicked human logical input, but without the imprecision of the human hand. Instead, the drill did what the operator wanted it to do, helping to eliminate unwanted variance in the drilling or boing process.
