METHOD FOR LOADING MEMORY IN ELECTRONIC CONTROLLER IN OPERATION BY USING FUZZY THEORY AND ELECTRONIC CONTROL DEVICE

摘要

PURPOSE: To minimize the size of a storage part and to perform an operation at a high calculation speed and at the excellent degree of a resolution by limiting the storage of a belonging relation function corresponding to a point where the value of the degree of the belonging relation of a function is not zero (not null) in a discussion area. CONSTITUTION: Signals from a system 9 to be controlled are converted to fuzzy logic information by a conversion device 2 and then sent to the storage part 5A and the specified storage of only a part of the information is executed there. The size of the storage part 5A is decided in response to the number of the non-zero values of the belonging relation function f (m) at the prescribed point (m) of the discussion area U provided with the maximum number of a non-null value and is far more compact than the size of the storage part obtained by a conventional method. The information stored in the storage part 5A is sent to a buffer part 8 and the restoration of the fuzzy logic information to be used in a calculation part 6 for an appropriate inference operation is implemented there. Thus, while minimizing a required storage capacity for a hardware, the operation is performed at the high calculation speed and at the high degree of the resolution.
