飞机仿真软件包dubsi10-2，可以与FDC tool（本站已有）一起使用的matlab/simulink仿真软件，主要对飞机的滚转姿态控制进行仿真研究，内有丰富的案例。(The Dutchroll Blockset for Simulink, DUBSI, is a stand-alone version of the blocklibrary BLOCKLIB_MISC in version 2.0 (or later) of the Flight Dynamics and Control (FDC) Toolbox, which is currently under development. It contains a number of general-purpose Simulink blocks, which can be used for more applications than flight dynamics research only. Both the FDC toolbox and the DUBSI blockset are copyrighted by M.O. Rauw see COPYING.TXT for more details. )
