Fuzzy Associative Memory System Application to a 4-fan Helicopter Control

Abstract

We propose a fuzzy associative memory system named Fuzzy Associative Memory Organizing Units System (FAMOUS) and show its usefulness for smulating human's training steps and human's association at helicopter control operations. FAMOUS has three features: 1) human friendly knowledge representation using fuzzy logic, 2) high ability for knowledge refining, 3) good inference results using association. The control knowledge is shown as the pair of “the condition (for example, the upper flying or the lower flying)” and “the operation (controller)” using fuzzy rule. The control knowledge is initially put into the fuzzy controller using FAMOUS. At the learning algorithm, each operation is individually trained under its condition, and the relationship between each condition and its operation is strengthened. FAMOUS recalls well-trained operations connection to the input condition, and controls a helicopter by synthesizing their operations. We actually apply FAMOUS to samall helicopter control, and show its usefulness.
