Fuzzy logic is an attempt to apply the easy design of logic controllers to the control of complex continuously varying systems. Basically, a measurement in a fuzzy logic system can be partly true.

The rules of the system are written in natural language and translated into fuzzy logic. For example, the design for a furnace would start with: "If the temperature is too high, reduce the fuel to the furnace. If the temperature is too low, increase the fuel to the furnace."

Measurements from the real world (such as the temperature of a furnace) are ''fuzzified'' and logic is calculated arithmetic, as opposed to [[Boolean logic]], and the outputs are ''de-fuzzified'' to control equipment.

When a robust fuzzy design is reduced to a single, quick calculation, it begins to resemble a conventional feedback loop solution and it might appear that the fuzzy design was unnecessary. However, the fuzzy logic paradigm may provide scalability for large control systems where conventional methods become unwieldy or costly to derive.{{cn|reason=See [[Talk:Control system#Fuzzy logic]]|date=April 2022}}

[[Fuzzy electronics]] is an electronic technology that uses fuzzy logic instead of the two-value logic more commonly used in [[digital electronics]].
