Since the introduction of fuzzy logic control theory, it has been successfully applied to a wide variety of ill-defined industrial processes. However, most of the fuzzy control examples use an inference method proposed by Mamdani. Here, we will use an inference method proposed by Tsukamoto based on Lukasiewicz logic to develop the control law and apply it to speed control of a DC servo motor system. Therefore, the main purpose of this paper is to develop the stability, robustness, and other behavior of the fuzzy controller and compare with the classical PI controller. Mathematical model will be developed, and used in the computer simulation to aid the selection of control parameters. Also, the feasibility of the fuzzy controller will be validated by laboratory experiments.
