视觉论坛的各种资源，除了视觉相关的模块有使用外，大部分的都不会使用，所以仅提供资源不能提供技术支持。资源的下载地址一般会同时提供NI官方地址和百度网盘的下载地址。某些工具包NI的地址失效或没有NI的下载地址，那视觉论坛也没有办法，只能尝试使用百度网盘地址下载；如果百度网盘的下载地址失效过期，可联系论坛客服更新。现在NI的下载服务器对我国IP地址不是很友好，有些时候速度很慢或大的资源下载很容易出错，这样会造成安装过程各种类型报错而无法安装。建议在下载完成后，对下载资源做校验和验证（NI一般会提供MD5或SHA256等），与官方或视觉论坛提供的校验和对比，一致就可以安装，如果不一致，则需要重新下载。视觉论坛早期下载的资源，那时候NI没有这么多限制，基本上都是正常下载的资源；后期下载的资源，都与NI的正确校验和对比过，保证是正确的资源才上传到百度网盘，所以百度网盘的资源基本上是正确的。校验和工具下载地址：

LabVIEW 2012 Control Design and Simulation Module Readme

System Requirements

• LabVIEW 2012 Full or Professional Development System (32-bit)

• At least 500 MB additional disk space for Control Design and Simulation Module support

• (Optional) LabVIEW MathScript RT Module—In LabVIEW 2009, LabVIEW MathScript became the LabVIEW MathScript RT Module. You cannot run VIs from previous versions of LabVIEW that contain MathScript Nodes until you install and activate the MathScript RT Module or remove the MathScript Nodes from the VIs. If you have already purchased the MathScript RT Module, select Help»Activate LabVIEW Components to activate the product.

• (Optional) LabVIEW SignalExpress—If you plan to install the LabVIEW Control Design Assistant, you first must install LabVIEW SignalExpress.
  

Limitations on Mac OS X and Linux

• LabVIEW Control Design Assistant

• Real-Time support
  

Installation/Upgrading Instructions

• Insert the NI LabVIEW 2012 Control Design and Simulation Module installation CD and open LabVIEW2012CDSim.mpkg located under the LabVIEW_2012Mac OS X directory.

• Select Continue to run a program to determine if the Control Design and Simulation Module can be installed on your system.

• Follow the instructions that appear on the screen and continue to the Destination Select screen.

• In the Destination Select screen, you must select the location where a compatible version of LabVIEW is installed. Otherwise, the installation will not complete.

• After you select the destination directory, continue to follow the instructions that appear on the screen.
  

• Log into the system as root.

• Insert the NI LabVIEW 2012 Control Design and Simulation Module installation CD. Use mount /mnt/cdrom to mount the CD. On some systems, the CD mounts automatically.

• To change the current directory to the mounted CD, enter the following command:
  
  cd /mnt/cdrom

• To run the installation script, enter the following command:
  
  sh ./INSTALL
  
  If you encounter the following message: "bad interpreter: Permission denied", the CD may not have mounted with executable permissions. To work around this, enter the following command: 
  
  /bin/sh ./INSTALL
  

Version 2012 Features and Changes

Designing Controllers Interactively

Collecting Signals at any Level of a Simulation Hierarchy

• Access Model Hierarchy function—Collects signals continuously, a point at a time, at run time. This function works similarly to a probe.

• Output Node of the Control & Simulation Loop—Collects and stores the value of a signal over the duration of the simulation for later access. This feature is similar to the Collector function.
  

New ODE and DAE Solvers

• Gear's Method

• Radau 5

• Radau 9

• Radau 13

• Radau [Variable Order]

• SDIRK 4
  

Configuring Model Parameters from MathScript Nodes

New Palettes

• Model Hierarchy—Contains functions that allow you to configure model parameters and collect signals in a simulation.

• Controllers—Contains functions that allow you to design and implement a controller based on the linear model of the system.
  

Enhanced VIs and Functions

• In the Control Design and Simulation Module 2011 and earlier, the Discrete Unit Delay function delays the input by a discrete time step of the size you specify. In the Control Design and Simulation Module 2012, this function is renamed Discrete Delay, and the function delays the input by the number of discrete time steps you specify.

• The CD Continuous Algebraic Riccati Equation and CD Discrete Algebraic Riccati Equation VIs include the following enhancements:
  

• These VIs include a new algorithm input that specifies the type of algorithm to use to solve the Riccati equation: Schur, Eigenvalues, QZ, or an automatic method of selecting an algorithm and solving the equation.

• In the Control Design and Simulation Module 2011 and earlier, these VIs return the relative residual of the Riccati solution in the Relative Residuals output. In the Control Design and Simulation Module 2012, these VIs return the absolute residual, and the output is renamed Residual.
  

• The CD Nyquist VI contains a Separate Contour? input, which, if TRUE, produces two plots: one that represents the positive frequencies and one for negative frequencies. Otherwise, this VI produces one plot for both the positive and negative frequencies. Separating the plots allows you to verify the direction of negative frequencies.

• The CD Sensitivity Functions VI include the following enhancements:
  

• The Noise Sensitivity (CS) output is renamed Controller Noise Sensitivity (CS).

• These VIs include a new Output Noise Sensitivity (-T) output, which returns the model equivalent to the sensitivity of noise to the output of the system.
  

• The CD All Margins and CD Gain and Phase Margin VIs include a Delay Margins and Delay Margin output, respectively, that returns information about delay margins in the system.

• In the Control Design and Simulation Module 2011 and earlier, the margins Control Design MathScript RT Module function returns only the gain margin frequencies of the input system model if you request zero or one output from the function. In the Control Design and Simulation Module 2012, margins returns a structure whose elements describe the gain, phase, and delay margins of the model.
  

Behavior Changes

• The Read/Write Model Parameters function is renamed the Access Model Hierarchy function.

• In the Control Design and Simulation Module 2011 and earlier, each instance of the CD Inverse Model polymorphic VI has an optional input that accepts a model. In the Control Design and Simulation Module 2012, this input is required, and the inputs are renamed Model In.
