Abstract

PURPOSE:To increase the setting accuracy and to facilitate an easy adjustment for the ternary ON-OFF control, by providing an wasteful time element corresponding to the wafteful time of a control subject in front of a feedback element. CONSTITUTION:The time constant T and again thetaF of feedback element 3 and 4 plus the wasteful time L of time elements 7 and 8 are set so that the stable control is obtained when the set value theta1 is varied in accordance with the time constant Tp and gain Kp of a control subject 2 plus the waste time Lp of time elements 5 and 6. For instance, when a control subject contains an integral element which is represented by the primary delay of the wasteful time, L=Lp, T=Tp and feedback gain thetaF= KpTp are satisfied respectively. As a result, not only the working but the adjustment can be extremely facilitated.
