This study investigates the use of Genetic Algorithms (GA) to design and implement of
Fuzzy Logic Controllers (FLC). A fuzzy logic is fully defined by its membership function.
What is the best to determine the membership function is the first question that has be
tackled. Thus it is important to select the accurate membership functions but these
methods possess one common weakness where conventional FLC use membership
function and control rules generated by human operator. The membership function
selection process is done with trial and error and it runs step by step which is too long in
solving the underlined the problem. GA have been successfully applied to solve many
optimization problems. This research proposes a method that may help users to determine
the membership function of FLC using the technique of GA optimization for the fastest
processing in solving the problems. The performance of GA can be further improved by
using different combinations of selection strategies, crossover and mutation methods, and
other genetic parameters such as population size, probability of crossover and mutation
rate. The data collection is based on the simulation results and the results refer to the
transient response specification is maximum overshoot. From the results presented, the
method which proposed is very helpful to determine membership function and it is clear
that the GA are very promising in improving the performance of the FLC to find the
optimum result. |
