Stabilized Control for Control Systems of Liquid Surface Vibration

Location control of a liquid tank and an Improvement of capacity sensor circuit

Abstract

A study of liquid surface vibration control for liquid transportation systems has been constructed and succeeded the surface control of the vibration system by present research. In this research, the location control that became indispensable in the liquid tank transportation etc. was added, and the effect of the location control was confirmed. On the other hand, the necessity for being improve the time base range of the sensor for future further stabilization and the enlargement of the system came out. Moreover, a correct liquid title has understood the one by the relative permittivity change of the liquid. In this research, the capacity voltage conversion circuit was changed for the measurement range improvement of the sensor. As a result, it reports that the measurement range improvement was obtained, and it is able to measure the liquid title that makes amends for the change in the relative permittivity.
