ABSTRACT:
Three separate fuzzy rule sets are applied to three corresponding fuzzy sets developed from various input parameters for providing a pitch engagement/mode selection management system and method for requesting disablement of a blade lock, for disabling such lock when the torque available matches the torque required, and for selecting a motor or brake for creating a differential speed between a rotating pitch change mechanism and a fan shaft of a turbine engine. A fuzzeresis rule set is disclosed for stabilizing the motor/brake mode selection fuzzy logic output.
