DLC is the ability to translate the a/c in the vertical plane without adjusting the aircraft attitude. The L1011 had DLC by use of spoilers which operated in a certain range. (Also the F16 Fighting Falcon-but thats FBW).
Active controls, again the L1011-500 had these in Gusta alleviation systems. Basically the ailerons would move to allleviate gust loads without any pilot input. (All done by magic boxes. PFM!!)
