On-line Identification of the LC Product in Coupled Resonant Circuits

We present an in-circuit approach for estimating the LC parameter in coupled resonant circuits. The theoretical background is discussed by presenting the models and performing a numerical sensitivity analysis. The method for estimating LC is based on noisy frequency response function measurements of the coupled resonant circuit. A practical implementation is presented and employed to validate the proposed method. Experimental results show that the proposed method provides an estimate of LC with a deviation of less than 4% with respect to LCR meter measurement results.
