luafaudes Tutorial: ftc_tutorial_reconf.lua

To run the below Lua script, cd to the tutorial section of the respective plug-in and enter luafaudes ftc_tutorial_reconf.lua at the command prompt. The script will read input data from ./tutorial/data/.

-- ftc_tutorial.lua
--
-- This Lua-script provides an application example for fault-hiding control 
-- via control reconfiguration.
