Description: 基于宽带调制转换器的一种新的压缩感知技术-Matlab package that simulates sampling by the analog system. The MWC consists of an RF front-end whose intermediate nodes are non-bandlimited signals. In this setting, computing the samples that would have been obtained by the hardware becomes a tricky task. This package sets the MWC parameters properly and also uses a dense time-grid in order to ensure sufficient approximation in computing the analog samples.
The simulations in this paper were generated by this package.
Usage:
(A) download from here and unzip.
(B) use start.m to run the simulations (can last many hours).
(C) use GenFigs.m to generate the figures from the saved results.

Description: 在MATLAB/Simulink环境中搭建了光伏发电系统模型,其采用最大功率点跟踪(MPPT)控制算法,并加入继电保护逻辑控制模块.通过PSASP的用户程序接口,可将该模型以电流源的形式接入电网模型进行暂态稳定计算.同时提出在电流源并网模式下并网光伏发电系统控制其与电网的无功功率交换为0,因此在潮流计算中可将光伏电站设为PQ节点,并设无功功率为0.CEPRI 36节点系统的仿真结果验证了该模型的正确性,并表明所提模型比常规同步电机二阶经典模型对电网故障的反应更为灵敏,但其对于改善全系统的暂态稳定性作用不大.-Built in MATLAB/Simulink environment, the photovoltaic power generation system model, which uses maximum power point tracking (MPPT) control algorithm and adding relay logic control module via the user program interface PSASP of the model can be in the form of a current source connected to the grid computing model for transient stability, while raised in the current source and network mode and grid-connected PV systems control the reactive power exchange with the grid is zero, so the flow calculation of photovoltaic power plants can be set to PQ node, reactive power and set the simulation results 0.CEPRI 36 node system to verify the correctness of the model and show that the proposed model is more sensitive than conventional synchronous motor response of the second-order classical model of grid failure, but the whole to improve transient stability is not the role of the system.

WHAT IS IT
This is a toolbox for computing ODEs or PDEs in BVPs using FEM in
1D, 2D and 3D.
* FEM1
this is the main routine for solving ODE BVPs using any combination
of Dirichlet, Neumann or Robin conditions.
* GENMAT1
called by FEM1 and is the core of the program. It generates the
matrices used for solving the linear equation system for the ODE.
* REFINE1
with this routine you can refine the mesh over certain critical
grid points. The the gridpoints will become nonuniformly linearly
spaced.
* TEST1
this is a test for the 1D case of FEM. Look through this example
carefully in order to fully understand how FEM1 works.
* FEM2.mat
contains examples over meshes/triangulations in 2D.
* PLOTGRID2
plot mesh/triangulation in 2D and put a number in each corresponding
element (triangle).
* QUADSPACE

Description: 边界节点法(Boundary Knot Method)是一种被广泛使用的无网格数值方法，具有编程容易、收敛速度快等优点，被广泛关注。边界节点法的主要思想是利用控制方程的非奇异一般解的线性组合来近似方程的解，通过配点法求解出未知系数。在这整个计算过程中保持了无网格的优势。鉴于边界节点法的优点，作者开发了基于边界节点法的MATLAB工具箱用以求解一些常见的椭圆形方程控制的物理问题如Helmholtz方程控制的声学问题等，为科学研究和工程应用提供了一个简便的工具。本软件可用于科学研究和实际工程计算，为各种实际工程提供有力的数值计算结果，也为广大的学者理解无网格方法提供了一些帮助。-Boundary knot method (Boundary Knot Method) is an meshless numerical methods are widely used, with programming easy, fast convergence, etc., has been widespread concern. The main idea of boundary knot method is to use a combination of non-linear singular general solution of equations to approximate solution of the equation by the collocation method for solving the unknown factor. Maintained without grid computing advantage in this whole process. Given the advantages of the boundary knot method, the authors developed a method based on boundary nodes MATLAB toolbox for solving some of the physical problems common elliptic equation control acoustic problems such as control of the Helmholtz equation, etc., for scientific research and engineering applications provide a simple Tool of. This software can be used for scientific research and practical engineering calculations, provide a powerful numerical results for a variety of practical projects, but also provides some help for Platform: |
