ABSTRACT:
A proportional control system for completely controlling a physical quantity under control without leaving an uncontrolable residue. In this control system, each time the system comes into an equilibrium state with a residue left uncontrolled, the manipulating quantity is changed to a new value which is proportional to the sum of a constant value equal to the manipulating quantity stabilized at the equilibrium and an instantaneous difference between a last previous equilibrium value of a physical quantity under control and an aiming value at which the physical quantity under control is to be kept finally.
