This paper, a nonlinear Proportional Integral Observer (PIO) is proposed for the estimation of the State of Charge (SOC) in lithium-ion batteries. On the basis of Lyapunov stability theory, the design of the proposed observer is underpinned by sufficient conditions, which are explicitly formulated through the use of Linear Matrix Inequality (LMI) constraints, to ensure the exponential stability and the H∞ performance. Simulation results are presented to demonstrate the efficacy of the proposed PIO in terms of its performance metrics.

摘要

This paper, a nonlinear Proportional Integral Observer (PIO) is proposed for the estimation of the State of Charge (SOC) in lithium-ion batteries. On the basis of Lyapunov stability theory, the design of the proposed observer is underpinned by sufficient conditions, which are explicitly formulated through the use of Linear Matrix Inequality (LMI) constraints, to ensure the exponential stability and the H∞ performance. Simulation results are presented to demonstrate the efficacy of the proposed PIO in terms of its performance metrics.
