Fuzzy Control of High-Accuracy Thermostatic Device in Double-Walled Container

摘要

This paper is concerned with temperature control of double-walled thermostaticcontainer, which is one of the most important element in the measuring device ofbarometric differences. In order to measure the barometric differences with highaccuracy, it is necessary for the container to be kept at constant temperature withinthe accuracy of O.Ol°c. But, due to random disturbances based on the fan andambient air temperature, the temperature in the container suffers an unfavorableinfluence on control accuracy. In order to realize a simple control strategy and highaccuracy, the fuzzy controller is applied and, through simulation studies, the validity is clarified.
