Comparative evaluation of a Fuzzy Logic Controller for speed control of DC motor applying different optimization techniques

摘要

In this paper, a Fuzzy PI Controller used for driving a separately excited DC motor, is compared to Conventional PI Controller, in terms of speed and load transient response ofthe motor. Further optimization of the Fuzzy PI Controller is performed using different central values for the output fuzzy sets, which are obtained from Simulink's Autotuning function. The effect of the selection of the output fuzzy sets central values is investigated and presented. The logic behind the selection of the Fuzzy Rules is also presented by analyzing the behavior of the DC motor at different operational regions. Performance and robustness results are presented and analyzed.
