Abstract
In the study, a new inference method which match the intuition of humanreasoning i sproposed. For each fuzy rule "if x is A, then y is B" the roposed inference method produces an output fuzzy subset B' according to the spatial relationship of input fuzzy subset A' and the antecedent A. The membership function of the output fuzzy subset B' is of the same shape as that of the input fuzzy subset A'. Moreover, the spatial relationship of B' is consistent with that of A and A'. Experiments on a simple single-input single-output example and the truck backer-parking control are performed to compare our proposed inference method with the Mamdani's method. These experiments show that our results compares favorably with that of the Mamdani's method.
