【Abstract】 A typical fuzzy controller with two inputs and one output is defined in terms of evenly distributed input membership functions, linear fuzzy control rules, Sum Product reasoning method, and unevenly distributed output membership functions. The analysis shows that the controller output is a combination of a global two dimensional multilevel relay and a local nonlinear controller. The role of the global multilevel relay and the local nonlinear controller in the control action is described quantitatively. The fuzzy controller output expressions are given with five fuzzy sets for each input. These results are also employed to the model reference adaptive fuzzy control of the pole balancing problem.更多还原
