我们提出了一个数字实现的连续时间观测器网络控制系统。我们引入了一个足够小的常数时间步长来构造连续时间观测器的欧拉模型参数化的时间步长。然后，我们提出了一个实时迭代的欧拉模型实现连续时间观测器的数字化，我们给出了充分条件，建议的数字实现可以估计采样时间的状态半全局和实际。数值例子来说明建议的数字实现的连续时间观测器。
We propose a digital implementation of continuous-time observers to networked control systems. We introduce a sufficiently small constant time step to construct the Euler model of continuous-time observers parameterized by this time step. Then, we propose a real-time iteration of this Euler model to implement continuous-time observers digitally and we give the sufficient conditions that the proposed digital implementation can estimate the state at sampling times semiglobally and practically. Numerical examples are also given to illustrate the proposed digital implementation of continuous-time observers.
