研究了参数不确定系统的鲁棒H∞估计问题。用MATLAB工具箱中的函数hinflmi来设计H∞估计器,是一种H∞优化设计,会导致过宽的估计器带宽。文中导出了一个用于H∞次优设计的线性矩阵不等式,利用这单一的LMI,选择一个次优值γ就可以控制带宽以减少估计误差。
The problem of robust H∞ estimation for parametric uncertain systems is studied. Designing the H∞ estimator using the hinflmi function in the MATLAB toolbox is a H∞-optimized design that results in a wide estimator bandwidth. In this paper, we derive a linear matrix inequality for H∞ suboptimal design. With this single LMI, choosing a suboptimal γ can control the bandwidth to reduce the estimation error.
