Learning algorithm for discourse of universe adaptive fuzzy controller

A new adaptive discourse of universe idea is brought forward in the thesis based on the interpolator mechanism of fuzzy controller in order to enhance the steady precision of control systems. The idea is that the discourse of universe of fuzzy controller reduces with the inputs decrease only when the control system approaches the steady state, the control rules are not changed at the same time. And the idea has been proved to be reasonable by theoretical analysis. Furthermore, an adaptive discourse of universe strategy is put forward. The method is tested to be effective by the control system simulation of steam pressure of boiler.
