卡尔曼滤波是一个“optimal recursive data processing algorithm(最优化自回归数据处理算法)’,它是根据上一状态的估计值和当前状态的观测值推出当前状态的估计值的滤波方法,是一种递推的过程.
首先引入一个离散控制过程的系统.该系统可用一个线性随机微分方程（Linear Stochastic Difference equation）来描述：
X(k)=A X(k-1)+B(U(k)+W(k)) （10）
再加上系统的测量值：
Y(k)=C X(k)+V(k) （11）
其中：X(k)——k时刻的系统状态,
U(k)——k时刻对系统的控制量.
A和B——系统参数,对于多模型系统,他们为矩阵.
Y(k)——k时刻的测量值,
C——测量系统的参数,对于多测量系统,C为矩阵.
W(k)和V(k)——过程和测量的噪声.他们被假设成高斯白噪声(White Gaussian Noise),他们的协方差（covariance ）分别是Q,R.

in addition,says Dr.David Ludwig,director of the Optimal Weight for Life Program,the routines are relatively easy for most families to adopt." This is a beautifully simple study.It makes a very important point,and one that needs to be noticed time and again.These are all behaviors that are within the reach of us all.

In this paper,the optimal tracking performance problem has been discussed for SISO networked control system with SNR constraints.We have derived explicit expressions of the minimal tracking error for systems with or without SNR constraints and,in particular,we have provided a characterization of the optimal performance subject to SNR constraints in two architectures of interest.The main result is obtained in terms of H2 criterion and spectral factorization technique.It is shown that the optimal performance is constrained by unstable poles a given plant,the power spectral density of a given reference signal and the SNR of a communication channel.The result clearly demonstrates how the SNR constraints may fundamentally degrade the system's tracking ability.An illustrative example has been given to demonstrate the proposed results.
Possible future extensions to this work include study on more general plants such as continuous-time plants with time delays,more complex control structure,and more communication channel constraints.
