Based on genetic algorithms (GAs), a method of designing a fuzzy logic
al controller for complex processes is proposed. After a brief overvie
w of GA, the selection of GA's control parameters is discussed for des
igning MIMO fuzzy control systems. We explained the optimization proce
dure of the fuzzy rules' selection on a large fuzzy input search space
. A double inverted pendulum device is used to test the effectiveness
of the design method based on GAs. Not only simulation results are sho
wn in the paper, but also the practical operation results are given.
