Dynamically adaptive fuzzy interval controller

摘要

A fuzzy logic controller that is dynamically adaptive to varying operating conditions. The controller remaps the intervals of the membership functions between a normalized universe of discourse and the real axis by use of an input fuzzy gain and an output fuzzy gain. The membership functions are also remapped within the universe of discourse through the use of a sensitivity index. Remapping of the membership functions allows the sensitivity of the controller to be adapted to optimize the controller's performance in changing operating conditions. This allows a robust controller to be implemented at low computational expense.
