A more effective fuzzy controller

In this paper, a more effective fuzzy controller is designed. Bypassing the complex trial-and-error designing steps, the parameters of fuzzy mechanism can be auto-regulated in accordance with the immediate change of system behaviors. In the fuzzy mechanism constructed, not only the error (e(k)) and error change (/spl Delta/e(k)) of the system output are considered, the error's acceleration (/spl delta//spl Delta/e(k)) is also included for constructing the overall fuzzy control system. Compared with the traditional fuzzy controller with two parameters, the fuzzy controller we developed can generate more appropriate force to control the system and then have better performances. Several different systems are implemented to demonstrate the feasibility and superiority of the controller we developed.
