U-Tube Manometer Calibration using ANFIS

This paper deals with the implementation of the Adaptive neuro fuzzy inference system (ANFIS) on a Xilinx based Field Programmable Gate Array Spartan-3E. The implemented hardware is then used to efficiently calibrate the U-Tube manometer, in which the relation between the level of mercury and the Capacitance developed across the Copper Plates of the manometer is highly non-linear. This system shows that the ANFIS can be implemented in hardware and can be used to calibrate the non-linear systems effectively.
