ACLIN is a Matlab program which can be applied to Simulink implementations of non-linear aircraft models in order to determine linearized versions of those models for certain flight-conditions.
ACLIN has been written for the Simulink system Beaver, which can be opened by typing
beaver
at the Matlab command line. It can also be applied to
other aircraft models in Simulink if they use exactly the
same definitions of the input and state vectors as the system
Beaver. However, if this is not the case, it is relatively easy to
adapt the source-code of the program, ACLIN.M, for the new
situation (it is recommended to take a closer look at the source-code to
see how it works).
