Binary Random Signalによる熱交換器の動特性試験

抄録

There have been proposed many methods to measure dynamic characteristics of linear processes, among them the correlation method using binary random test signal is powerful, because the dynamics can be measured fairly accurately with small amplitude test signal, and the test signal can easily be constructed and be manipulated for its binary characteristics.
In this paper, the possibility to apply this method to industrial processes is examined by using heat exchanger plant. Experimental results of this heat exchanger test are compared with the experimental results obtained from the pulse test method and with the theoretical data, and good coincedence is observed. The computational procedure to calculate the dynamic characteristics and the considerations about a period of the test signal NΔ, minimum pulse width Δ and the data sampling interval δt are also presented.
