对于给定的雷达信号参数,对线性调频信号时域与频域的波形仿真(Radar signal for a given parameter, the linear frequency modulated signal time-domain and frequency domain waveform simulation)

non linear Ant colony optimization for continous problem

这个有中文注释，看得明白，采用的是通用的平面波展开法,主要是基于mtlab的程序。( The Chinese have a comment, understand it, Using common plane wave expansion method, Mainly based on the mtlab procedures.)

说明：  卡尔曼滤波，matlab代码 能够直接跑(Kalman filter, matlab code can be run directly)

主程序arma2Ddemo是对模拟图像的2DAR和ARMA参数估计。(arma2Ddemo: See and run the demo arma2Ddemo for an example of 2D AR and ARMA parameters estimation from simulated images. - sim_ar2d: generation of simulated 2D AR process. - sim_arma2d: generation of simulated 2D ARMA process. - ar2d: solves 2D yule walker to estimate AR parameters - arma2d: estimation of 2D ARMA parameters. First step: estimation of the gaussian input by inv_ar2d, Second step: linear system solution to estimates simultaneously AR and MA parameters, as explained in [1]. - inv_ar2d: first step in arma2d. Filters through inverse filter 1/AR an AR process, to generate its innovation Gaussian signal. It is used here to estimate the Gaussian noise input to the ARMA 2D process, approximating the ARMA model to a high order AR model. - poles2coeff: converts poles chosen by user to AR or MA coefficients (support function) )

永磁同步电机simulink仿真 (Permanent magnet synchronous motor simulink simulation)

说明：  电力电子变换器采用重复控制策略。在反馈回路中设置一个内部模型，使该内部模型能够很好地描述系统外部信号特性，通过该模型的作用可使系统获得理想的指令跟踪特性，具有较强的扰动抑制能力。(Repetitive Control Strategy for Power Electronic Converter.An internal model is set up in the feedback loop, which can describe the external signal characteristics of the system well. Through the function of this model, the system can obtain ideal command tracking characteristics, and has strong disturbance rejection ability.)

GTRACK Track mouse position and show coordinates in figure title. Once GTRACK is active the mouse position is constantly tracked and printed on the current figure title. A left-click will print the coordinates in the command line and store them. Clicking the mouse right button deactivates GTRACK.
