Rauw (rauw@dutchroll.com) Haarlem, The Netherlands February 1998, July 1998, June 2000, May 2001, December 2001, May 2002 ABSTRACT ======== The Flight Dynamics and Control (FDC) toolbox is a graphical software environment for the design and analysis of aircraft dynamics and control systems, based upon Matlab and Simulink. It simplifies the Flight Control System design process by integrating linear and non-linear analysis within one software environment. The toolbox has been set up around a general non-linear aircraft model which has been constructed in a modular way, thus providing maximal flexibility to the user. The aircraft model can be accessed by means of the graphical user-interface of Simulink. The toolbox also includes some analytical Matlab routines for extracting steady-state flight conditions and determining linearized models for user-specified operating points, Simulink models of atmospheric disturbances and radio-navigation systems, extensive models of a `classical' autopilot, and several help-utilities which simplify the handling of the systems and tools. Keywords: Flight Control System Design, Aircraft Modeling, Non-linear Simulation, Computer Assisted Design ABOUT THE CURRENT FDC DISTRIBUTION PACKAGE ========================================== This is the third minor release of FDC 1.3, which is identical to the previous release (FDC 1.3 Service Release 2), except for its licensing terms. This version is the first to be licensed under the Dutchroll Open Source Software License (DOSSL), version 1.0; see LICENSE.TXT for more information. FDC 1.3.3 requires Matlab 5.1 / Simulink 2.1 or newer. If you use Matlab 4.x / Simulink 1.x, you can use version 1.2 of the toolbox, which is also available via the FDC homepage (see below). FDC 1.3.3 has also been tested successfully with Matlab 5.3 / Simulink 3.0 and Matlab 6.0 / Simulink 4.0. If you encounter any problems with newer Matlab versions, please let me know. Any suggestions for further improvements are also welcome; the contact address is given at the bottom of this document. FDC 1.3.3 has been stored in the file FDC13-3.ZIP. Detailed documentation for this particular version is not available, but the user-manual for the previous FDC version (1.2) will be of great help. This user-manual is available in PostScript and PDF format via the FDC home- page (see below). FDC 1.3.3 includes HTML-based help-texts for on-line assistance, which will also help to get you started. If you are able to access the 'Matlab Help Desk' from your copy of Matlab, the HTML help-function for FDC 1.3 should work correctly as well. Installing the FDC toolbox ========================== Note: the path-notations in this section are in Windows 9x format. Replace this by the appropriate format for other operating systems. 1. Copy the file FDC13-3.ZIP to a temporary directory. 2. Unpack FDC13-3.ZIP to a suitable destination directory. It is recommended to create a subdirectory (subdirectory) FDC13 in the TOOLBOX directory of Matlab and use this as destination for FDC 1.3.3. For example, if you have installed Matlab in the directory C:\MATLAB, the recommended destination for FDC 1.3 SR2 will be C:\MATLAB\TOOLBOX\FDC13). It is necessary to retain the FDC directory structure when unpacking. For instance, if you use PKUNZIP for MS-DOS, this can be done by including the -d option to the pkunzip command-line. Other unpack routines, such as Winzip, will probably do this automatically. NOTE: when unpacked, FDC 1.3.3 requires about 4.8 Mbytes of disk space! 3. Now start Matlab 5.1 (or later). The Matlab search path should now be enhanced with the FDC directories. It is recommended to add the FDC root- directory to the Matlab path permanently, since this simplifies future use. This can be done with the Matlab utility EDITPATH.M. If you followed the recommendations above, the FDC root-directory will be something like C:\MATLAB\TOOLBOX\FDC13. NOTE: FDC 1.3.3 does NOT support directory names that contain spaces! Therefore, if you have installed Matlab to C:\Program Files\Matlab, it is recommended to install FDC 1.3.3 into C:\FDC13 or any other directory that does not contain spaces. Select this directory and select 'Add to path', 'Add to back', and 'OK'. Next, select 'Save settings' to make this a permanent change. (Alternatively, if you don't want to have the FDC root-directory permanently saved to the search-path, use the CHDIR command to go to this root-directory, e.g.: chdir c:\matlab\toolbox\fdc13, and proceed with the following step.) 4. Run FDC.M. After some welcome messages, this routine will initialize the FDC toolbox and enhance the search-path with the remaining FDC subdirectories. You will be asked to check whether the FDC path is correct. In practice, only the FDC root-directory may be faulty, especially if you did not install the toolbox to the \matlab\toolbox\fdc13 directory. So pay special attention to the FDC root-directory. If you are convinced that everything is allright, and if you're not planning to change anything in the nearby future, press 'S' to suppress the directory-check for future FDC sessions. 5. The toolbox has now been installed completely. You now have the option to go to the main FDC library, view the HTML-based help texts, or view the contents of the toolbox-directories. The last option will show ALL Matlab toolboxes, not only FDC 1.3.3 - double-clicking the directory names will yield more information about their contents. If you don't want any of these options, choose 'Cancel'. Opening the FDC library is then still possible by typing 'fdclib' (without the quotes) at the Matlab command-line, and the index-page of the HTML help-texts can be accessed by typing 'fdchelp index' at the command-line. It is recommended to view the *.TXT files in the subdirectory DOC for more information: CONTENTS.TXT gives a complete overview of the files from FDC 1.3 HISTORY.TXT gives an overview of the FDC development since the very fist version LICENSE.TXT license agreement README1.TXT this file README2.TXT gives some background information about compatibility problems you may encounter when upgrading from a previous version of the FDC toolbox SUPPORT.TXT gives information about the user-support for FDC 1.3 WHATSNEW.TXT lists the new features in FDC 1.3 6. If you use Matlab 5.2 / Simulink 2.2 (i.e. release 10), or newer, you will probably receive the following warning message when you try to open any Simulink system from the FDC toolbox: Warning: Run 'slupdate('[system name]')' to convert the block diagram to the format of the current version of Simulink To el
