Temperature Control of Microwave Catalysis Continuous Reaction Experiment System

A new type of fuzzy control was applied to control intelligently the temperature of microwave catalysis reaction in the continuous pharmacy. The fuzzy control system has a two dimensional single variable input, increment output and multi groups of self-adjustment genes. To improve the operation rate, the fuzzy control table founded in the design process was looked up in running. Multi groups of genes were used. The control dead-zones were reduced. The control precision was improved. An industry computer was used as a controller. The control algorithm was carried out in an industrial control computer. The control cycle period and the two group genes were adjusted in an experiment. The range of steady-state error is only ±1°C. The control precision and the stability of this system are suitable to the temperature control of the microwave catalysis reaction.
