| Abstract: | The interpolation model of typical fuzzy PID controllers was deduced, which used full-overlapped triangular normal membership functions for input variables, and PID expressions for reasoning outputs. The essential character of typical fuzzy PID controllers was discovered to some extent. The model can be used to develop a fast and precise control algorithm in practical use. The parameter optimization of this kind of fuzzy controllers was studied in detail by means of its precise analytical interpolation model. A system simulation example was conduced to demonstrate the optimal design method. |
