Abstract
In recent years the behavioure of on-off control system with feedback compensation has been improved, and some setting conditions of the on-off controller have been proposed. However one of the defects by these setting conditions in practice is that the offset cannot be reduced to zero.
In order to get time optimal response and zero offset when the set point is largely changed stepwise a new setting condition of the feedback compensated on-off controller which has the first order lag and dead time element is proposed.
As a result of the analog computer study on the responses of the on-off control system, it is found that the proposed setting condition is especially effective to the large step change of the set point
