使用matlab的simpower进行电力电子电路仿真，这个是英文文档(Use matlab' s simpower to power electronic circuit simulation, this is the English document)

说明：  数字通信塔，用增量调制将模拟信号转换为离散的数字信号，在基带中采用Miller码编码，信道编码采用汉明码，调制方式采用PSK,通过AWGN信道传输。(A digital communication system，PCM encoding converts analog signals into discrete digital signal, uses Miller code coding in baseband and Hamming code in channel coding , then PSK modulation way )

车辆四分之一模型的matlab/simulink仿真，包含主动悬架的simulink控制器搭建(Matlab / Simulink simulation of vehicle quarter model, Simulink controller construction including active suspension)

说明：  E4 tool for matlab, for modeling time series

This file compares three different versions of the Kalman filter. The Kalman filter is used for recursive parameter estimation. The Kalman filter can handle noisy measurements. The first implemented filter (fcn_KF) is the Kalman filter with standard update of the covariance matrix P. The covariance matrix reflects the uncertainties of the predictions. To improve the numerical stability Potter developed a square root update (fcn_KF_SRP) of the covariance matrix P. Another version is the square root covariance update via triangularization (fcn_KF_SRT). This file generates a model. Then the three Kalman filters perform an estimation of the model parameter. At the end the results are compared. Sources: Simon, D. (2006): Optimal state estimation Kaminski, P. (1971): Discrete Square Root Filtering: A Survey of Current Techniques Golub, G.
