Abstract:
A compiled fuzzy logic control system for controlling a process, comprising:means for sensing at least two continuously defined state variables of the process;means for receiving the sensed state variables from the sensing means;a memory having a look-up table stored therein at a plurality of memory locations, the look-up table being a compilation of values derived from executing a fuzzy logic rule base for the sensed state variables, such that each of said plurality of memory locations stores a value representative of an output derived from an operation of the fuzzy logic rule base, wherein a portion of the stored values are representative of the output from executing a single corresponding rule of the fuzzy logic rule base and other stored values are dependent on the outputs from executing a corresponding plurality of rules of the fuzzy logic rule base;means for generating an address for the sensed state variables to a location in the look-up table of the memory;means for reading the look-up table in the memory location corresponding to the generated address and outputting the stored value derived from executing the fuzzy logic rule base therefrom; andactuating means coupled to the reading means for receiving the stored value and outputting a control action to the process in accordance with the stored value derived from executing the fuzzy logic rule base.
