DUBSI  the Dutchroll Blockset for Simulink
Blocklibrary: DUBSI


The Dutchroll Blockset for Simulink (in short: DUBSI) is a collection of several generalpurpose Simulink blocks. The blockset is also available as the blocklibrary BLOCKLIB_MISC of the Flight Dynamics and Control Toolbox; DUBSI is the standalone version of that blocklibrary. Why Dutchroll?The 'Dutch Roll' is one of the characteristic motions of an airplane. It is a combination of rolling and yawing, which results in an elliptic motion of the wingtips. Because of this close relation with aircraft dynamics, the website for the Flight Dynamics and Control (FDC) Toolbox was named 'www.dutchroll.com' and all software projects and publications which have any relation with the FDC toolbox will be published under the 'Dutchroll Software' label. The DUBSI blocksetThe picture below gives an overview of the blockset. Click on the figure to see a fullsize screenshot; then click on any individual block in that screenshot for help about that particular block. Summary of the blocksThe blockset has been subdivided in 7 sections: Sinks, Gains, Signals & Switches, Discrete, Nonlinear, and Transformations. These sections largely mirror the usual Simulink libraries, except for the Transformations section, which contains three rotation matrices that can be used to express a vector in a different, rotated, reference frame. The 7 sections contain the following blocks: Sources
Sinks
Gains
Signals & Switches
Discrete
Nonlinear
Transformations
