Research Abstract |
The purpose of this research is to develop temperature control of a double-walled thermostatic container, which is one of most important element in the measuring device for measurements of the ventilation in tunnels. If we demand the measuring accuracy within (<minus-plus>) 1 Pa in this device, it is necessary for container to be kept at a constant temperature within the accuracy of 3/1000 ゚C.But due to steady-state error based on the variation of ambient air temperature, the temperature in the container suffers an unfavorable influence on control accurac In order to realize temperature control of high accuracy, the Self-tuning Control is applied and, through simulation and experimental studies, it is verified for the control accuracy in the inner space to be always kept within 0.01゚C.Then, this control strategy by computer control has the possibility of practical use for the real system.
