Abstract
PURPOSE: To realize the driving method for the proportional controller which is capable of performing an accurate proportional control in accordance with the operation signals at all times by feeding back the average level of the voltage caused by the conducting current of the proportional controller to the operation signals.
CONSTITUTION: A comparison is given through circuit 3 between the signal indicating the current value delivered from circuit 1 and the signal indicating the target value delivered from circuit 2. Based on this difference of comparison, the analog operation signals are delivered to point (a). Then the driving signals of the pulse row featuring the duty variation according to the operation signals are produced via triangular wave generation circuit 9, and the ON/OFF control is given to transistor 10 to control the conduction of solenoid coil 11 of the proportional controller. In this case, the voltage of resistance 12 caused by the conducting current of coil 11 is smoothed through circuit 13 to be turned to the average voltage which is negatively fed back to differential integrating circuit 5. As a result, the effect of the fluctuation of the power voltage, for example, can be compensated, thus ensuring an accurate control.
