Variable-Construction Adaptive Fuzzy Control System and its Application

This article presents a control system based on the concept as follows: At first, according to the performance indices of the controlled object a set of fuzzy variables is constructed, then it constructs a set of fuzzy control rules which is used to change the parameters of the fuzzy control. Based on the control this system is added with the variable-construction and adaptive control to modify the relevant parameters and rules in the control strategy. The Robustness of the controlled system is obviously improved. This control method was applied in the temperature control of dryers in a factory. Experiments show that this system has good Robustness and stableness.
