针对具有有界范数噪声和未知输入信号的隐模切换线性系统，提出了一种同时实现模式、输入和状态集值观测器的方法。观测器由两部分组成：（i）一组模式匹配观测器和（ii）模式估计器。每个模式匹配观测器递归地输出模式匹配的兼容状态和未知输入的集合，而模式估计器使用基于残差的准则来消除不兼容模式。然后，状态和未知输入的估计集是所有兼容模式上的模式匹配估计的并集。此外，充分的条件，以保证消除所有的假模式和展示我们的方法的有效性，使用一个说明性的例子。
A simultaneous mode, input and state set-valued observer is proposed for hidden mode switched linear systems with bounded-norm noise and unknown input signals. The observer consists of two constituents: (i) a bank of mode-matched observers and (ii) a mode estimator. Each mode-matched observer recursively outputs the mode-matched sets of compatible states and unknown inputs, while the mode estimator eliminates incompatible modes, using a residual-based criterion. Then, the estimated sets of states and unknown inputs are the union of the mode-matched estimates over all compatible modes. Moreover, sufficient conditions to guarantee the elimination of all false modes are provided and the effectiveness of our approach is exhibited using an illustrative example.
