摘要： PROBLEM TO BE SOLVED: To find a residual contamination amount including a VI value and a CO value in a tunnel from various measurements including a VI value and a traffic density in the tunnel by using a tunnel model and find a required ventilation amount therefrom to control a tunnel ventilating device which is involved in unstable control or poor control precision when there is a noise or an abnormal value in the VI value. SOLUTION: A smoothing part 36 is provided for taking up a VI value to eliminate the take-up of a noise or an abnormal value. The computation result of a residual contamination amount computation part 35 is smoothed and measurements including a CO value and others are smoothed. If there are abnormal values in the measurements, a previous measurement becomes a current measurement. To find a contamination amount from a traffic density by distinguishing large vehicles from small vehicles, a correcting coefficient is automatically adjusted and an interval for data collection for a traffic density is adjusted.

摘要： PROBLEM TO BE SOLVED: To provide the adjustment method which can easily decide the PID parameter of optimum value to design a stable control system and also can automatically adjust a PID controller by the simulation of computer application by adjusting even the gain of an integration term when the PID parameter is adjusted by the critical sensitivity method. SOLUTION: When the PID parameter is decided by the critical sensitivity method the integration time and the differentiation time are set at the maximum value (T1 =∞) and the minimum value (TD=0) respectively and the proportional gain Kp is increased up to its maximum value from the minimum value in a normal application range. If the difference (y) is negative between the 1st and 2nd peaks, the sustained oscillation is decided. Thus a 1st step is prepared to set the proportional gain at Kpm of the relevant time point together with a 2nd step where the integration time is reduced down to its minimum value from the maximum value in the normal application range and then set at T1 M that produces the least error against the input with the porportional gain and the differentiation time are set at 0.2Kpm and the minimum value (TD=0) respectively. Then the differentiation time TD is set at the value obtained by multiplying the value T1 M by a certain coefficient.
