Given an unknown input image, the recognition system projects the image to eigenspace.
      
The unique feature of the method is that it extends cycle-level architectural simulation techniques to enable symbolic execution with unknown input data values; it uses alternative instruction semantics to handle unknown operands.

The problem of the design of observers for a class of nonlinear Lipschitz descriptor systems with unknown inputs is con-sidered.The objectives are twofolds.Firstly,the design of an unknown input observer for nonlinear descriptor systems is studied.Secondly,if the disturbance is not possible,robust observer for such systems is proposed.The existence conditions of these ob-servers are given and proved.A detailed example is presented for the method.

考虑了一类含有未知输入的Lipschitz非线性广义系统的鲁棒观测器设计问题.设计了一种非线性广义系统的未知输入观测器;当系统干扰无法消除时,设计出了一种鲁棒观测器.证明了它们的存在判据,并给出了具体的设计步骤.算例说明了方法的有效性.

This paper focuses on the fault detection for singular stochastic systems with unknown inputs.Under the reasonable conditions,a reduced-order subsystem,which is decoupled from the unknown disturbances,is separated from the original system by using a state transform.For this stochastic subsystem,a stable filter is designed and the statistics of the output residual are given.Based on these results,the fault detection is realized.

研究了含未知输入的广义离散系统的输入解耦观测器设计问题。在系统因果能控的条件下,通过系统输入状态对的非奇异变换,把此问题等价地转化成正常状态离散系统的相应问题。用大家熟知的方法设计正常状态离散系统的观测器,从而得到广义离散系统的输入解耦观测器。然后用广义离散系统的观测器状态与系统输出的线性组合渐近估计广义离散系统的状态与未知输入。
