摘要
基于等价空间方法研究离散时间Markov跳跃系统的故障估计问题,通过引入新的性能指标来评估故障估计的性能,建立基于等价空间的故障估计问题和特定二次型最小化问题之间的关系,基于此得到最小化问题可解的充分必要条件,并给出等价矩阵的统一解析解。最后,通过算例验证所提方法的有效性。
This paper deals with the problem of parity space based fault estimation problem for a class of discrete- time Markovian jump systems. A new design criteria is introduced to evaluate the fault estimation performance index, and a relationship between the parity space-based fault estimation and the minimum problem of certain matrix quadratic form is built. Based on this, a necessary and sufficient condition for the minimum problem is derived, and a unified analytic solution to the parity matrices is obtained. A numerical example is given to illustrate the effectiveness of the proposed method.
