Kalman filter application

HB_TO_MM is a MATLAB program which accepts the name of a file containing a sparse matrix in the Harwell Boeing Sparse Matrix File Format, and which reads that data and writes a corresponding Matrix Market sparse matrix file.

说明：  针对Z变换法无法求取相邻采样点之间的输出响应的局限，利用MATLAB程 序语言，对单位负反馈系统的改进z变换法进行了程序设计。通过simulink仿真的实验，证 明该程序运算快速、准确，使用方便。(For the Z transform method can not strike between adjacent sampling points in response to the limitations of the output, using MATLAB programming language, a negative feedback system of units of the z transform method to improve the program design. Through simulink simulation experiments show that the procedures for computing fast, accurate and easy to use.)

该SIMULINK程序描述的是有源滤波器(APF)挂载在电网后滤除了电网的谐波电流。(This demonstration illustrates the use of a shunt active harmonic filter (AHF) to minimize the harmonic content propagated to the source a non-linear load.)

可以利用拉格朗日插值方法解决多项式逼近问题(Lagrange interpolation method can be used to solve the problem of polynomial approximation)

说明：  假定均匀线列阵的阵元数为16。入射平面波为是频率为62.5Hz的正弦信号。阵元间距为波长的1/2。系统采样频率为1kHz，观测时间为0.4s，阵列加权方式为均匀加权，分别给出： (a)当平面波信号分别从0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100度方向入射时，主瓣指向90度方向的波束形成器的输出序列。(It is assumed that the number of elements of uniform linear array is 16.The incident plane wave is a sinusoidal signal with a frequency of 62.5Hz. The element spacing is 1/2 of the wavelength. The sampling frequency of the system is 1 kHz.The sampling frequency of the system is 1 kHz, the observation time is 0.4 s, and the array weighting mode is uniform weighting.)
