It looks like you might have gotten a bit confused by the naming convention of some files.
Firstly, I'd suggest that you use format_adsys (all lowercase) for your plugin's frankenstyle name, for consistency with other plugins and to lessen the chance of mistyping it.
The files in lang/en/ and backup/moodle2/ are the only ones that should use the frankenstyle name. The others should be called e.g. lib.php not format_adsys_lib.php. Other than that, posting the contents of your version.php might help someone spot why your plugin is not being recognised.
