Aim at the problem of accurate auto-ingredient in fine chemical engineering and building profession,based on PLC,a method which adopt the factor self-modify fuzzy control was proposed,and the factor self-modify fuzzy controller which is inside the whole theory area scope of the error margin,the error margin variety rate and the control quantity language variety was designed.

Self-adjustable expert fuzzy control of deep ocean mining robot;

Improvement in expert fuzzy control based combustion control system of reheating furnace;

In this paper, a self-adjustable expert fuzzy controller is presented to control deep seabed self-propelled tracked mining vehicle to follow specified path.

A new fuzzy expert control method was brought forward by synthetically using the techniques of on-line intelligent identification, multi-control-mode, self-decision mechanism and self-adjustment of universe of discourse.

The rule base, the inference engine and the mechanism of the self regulation of universe of discourse in the late developed fuzzy expert controller for aluminum reduction cells were elaborated.

The corresponding fuzzy expert control system for air temperature in greenhouse was established by using the Simulink tools of MATLAB, including the choosing of variables, definition of fuzzy sets, grade partition of the universes, choosing of membership functions and establishment of the fuzzy control rules.

Furthermore, the expert-fuzzy control is adopted to control the temperature of the secondary supplying water of each substation.

Hardware of the expert controller takes DSP as core,the fuzzy-expert control technology is adopted in the software.
