Sampled-data observer for supercapacitor parameters estimation under NEDC cycles

Résumé

In this paper, a parameters estimation method of a supercapacitor is proposed through NEDC cycles. The goal is to provide a fast and good online estimation of key parameters (resistance and capacitance) as they are useful for estimating of its State Of Charge (SOF) and State Of Health (SOH). A new continuous-discrete nonlinear observer is designed to estimate, both states and parameters using sampled measurements. This observer is proved to be globally exponentially convergent by a sufficient condition about the sampling time. Experimental results highlight good performances of the observer in online parameters estimation.
