Abstract
A fuzzy logic algorithm utilizes a single rule to produce a varying output signal. A plurality of input signal values are received from a plurality of sensors. A predetermined combination of a plurality of membership functions in the single fuzzy logic rule are defined in which a first instance of the predetermined combination based on a first set of inputs yields a first output signal defined by a first and second axis. A second instance of the predetermined combination based on a second set of inputs different from the first set of inputs yields a second output signal substantially identical to the first output signal, except the second output signal is shifted along one of the first and second axes. A controller produces digital output signals based on the first and second output signals to produce the varying output signal.
