Abstract文中提出一种基于H∞观测器电池荷电状态SOC估计方法。在传统电池SOC估计方法中,常常把电池开路电压OCV与SOC之间的关系看作是静态线性关系。实际上,电池OCV与SOC之间是随着电池周围环境变化而变化,是一种动态关系;因而如果将电池OCV与SOC之间看作是静态关系,可能导致较大SOC估计误差。根据电池OCV与SOC之间动态关系,将电池系统建模成一种非线性系统,随后设计一种H∞观测器估计电池SOC。在高压输电线路巡检机器人样机中进行了实验研究,实验结果验证了所提方法的有效性。
Other AbstractThis paper, a battery state of charge (SOC) estimation methods based on an H∞ observer is proposed. In conventional SOC estimation methods, it is assumed that the relationship between battery open circuit voltage open circuit voltage (OCV) and SOC is linear and static. However, the relationship is only piecewisely linear in practice and varies with the ambient environment. The large SOC estimation error can be resulted in with the static relationship. A battery is modeled as a nonlinear system, and an H∞ ob...
