An Efficient Approach for Optimization of Nonlinearity Response in Linear Variable Differential Transformer

Abstract

This paper proposes an efficient approach for optimization of non-linearity response reflected in output of Linear Variable Differential Transformer / in Linear Variable Differential Transducer (LVDT). Customarily, the non-linearity in LVDT was reduced by windings/coils tuning, which was very difficult to get fine tune. This problematic situation can overawe by implementation of the projected scheme. The Functional link artificial neural network (Fun-LANN) has been effectively implemented for nonlinear optimization of the senor’s response. The effectiveness of the proposed method is demonstrated through MATLAB simulation and the response has validated with various nonlinear effects. The experimental analysis of the proposed scheme produces high sensitivity, good linearity and insensitivity to excitation variations.
