Variable-Construction of an Adaptive Control System and Its Application

An integrated control method is presented here based on variable-construction, adaptive and fuzzy control strategy. First, according to the performance indices of a controlled object the fuzzy variable set is constructed, then it constructs a set of fuzzy control rules which is used to change control parameters of the fuzzy control. Based on the fuzzy control this system is added with variable-construction and adaptive control to improve the quality of the system control and adapt controlled objects to the structural parameter variation. This control method was applied in the temperature control of dryers in a factory. Experiments show that this system has good Robustness and stableness.
