Has anyone tried to add lens filter to AE100 to improve the "black" shading performance. pls share your experience, thanks!

Yes. Many of us are using a Hoya HMC-FLD. Search the forum for more info.

I'm using a Neutral Density filter (ND2/.3/1 f-stop depending on brand) and I'm quite satisfied with the results. A 52mm fits nicely into the lens, but I'm finding some light reflections from it, so I'd advise going with something bigger, even if it's uglier.
