Fuzzy logic approach for airborne gravimeter power system control

Gravity survey measures variations in the Earth's gravitational field arising from the differences in the density between subsurface rocks. Gravity survey is used nowadays to locate minerals, petroleum resources, and ground-water reservoirs. In the past few years, gravity exploration has witnessed significant advances, especially in airborne gravity gradiometer instrument technology to cover large areas of ground in a small amount of time. The main operational drawback of the airborne gravity is the requirement for the gravimeter system to remain powered continuously. This paper presents a development of power monitoring system using fuzzy logic to control the power consumption and avoid any fluctuations between different power sources that feed the gravimeter. The approach was tested and functioned properly as a mean to reduce the risk of unexpected shortage of power.
