Fuzzy Control (ファジー コントロール, Fajī Kontorōru) is a three-piece Japanese rock band currently signed to DCT Records. They gained prominence in Japan after being featured as vocalists and musicians on Dreams Come True's singles "Good Bye My School Days" and "Sono Saki e". Fuzzy Control has played at the 2005 Summer Sonic Festival and their single "Think Twice" was used as the ending theme for the Mushiking: King of the Beetles anime. They also appeared at the 60th NHK Kōhaku Uta Gassen, having been featured on Dreams Come True's "Sono Saki e".
A fuzzy control system is a control system based on fuzzy logic—a mathematical system that analyzes analog input values in terms of logical variables that take on continuous values between 0 and 1, in contrast to classical or digital logic, which operates on discrete values of either 1 or 0 (true or false, respectively).
Fuzzy logic is widely used in machine control. The term "fuzzy" refers to the fact that the logic involved can deal with concepts that cannot be expressed as the "true" or "false" but rather as "partially true". Although alternative approaches such as genetic algorithms and neural networks can perform just as well as fuzzy logic in many cases, fuzzy logic has the advantage that the solution to the problem can be cast in terms that human operators can understand, so that their experience can be used in the design of the controller. This makes it easier to mechanize tasks that are already successfully performed by humans..
