摘要:
当噪声的统计特性未知时,基于锂电池的戴维宁等效电路模型并使用扩展卡尔曼滤波(EKF)方法进行在线估算锂电池的荷电状态,会导致精确度迅速下降,容易发散。本文使用Sage-Husa自适应滤波算法来代替扩展卡尔曼滤波算法,并利用Matlab进行建模仿真比较。仿真结果误差大幅度减小,曲线趋于平滑。结果表明,在干扰噪声未知的环境下,基于Sage-Husa自适应滤波的荷电状态估计可以提高荷电状态在线估计的精度。
Abstract:
When the statistical characteristics of noise is unknown, the state of charge of lithium batteries in real time can be estimated by the extended Kalman filter(EKF),based on equivalent circuit of Thevenin model, thus the accuracy is decreased rapidly and dispersed easily. Instead of the traditional EKF, Sage-Husa adaptive filter algorithm was used to study the problem, and the data from experiments were modeled and simulated with Matlab software. The simulation results showed that the error was greatly reduced and the curve was smooth. The Sage-Huasa adaptive filter algorithim could improve the real-time estimation of charge state.
