本文主要研究多输入多输出非线性切换系统的未知输入观测器的构造问题。其思想是在不同的观测器之间切换，以估计每个暂态周期的未知状态和未测量的输入，并选择不同的增益值以减少误差估计。给出了保证所设计观测器收敛的理论稳定性分析。取而代之的是，为了评估所提出的混合观测器的效率，给出了一个四箱过程的仿真结果。
The main topic of this paper is the problem of constructing unknown inputs observers for MIMO nonlinear switched systems. The idea is to switch between different observers to estimate the unknown states and the non-measured inputs for every transient’s periods with the choice of various values of the gain to reduce the error estimation. Theoretical stability analysis is derived to ensure the convergence of the designed observer. Instead, simulation results on a quadruple tank process are given in order to assess the efficiency of the proposed hybrid observers.
