Not a trilogy, but I just re-read "The Moon is a Harsh Mistress" by Heinlein. Published in 1966, it's about AI and revolution of exploited moon colonists against Earth. It struck me how much The Expanse (book and TV series) seemed to borrow from some of the basic premises. Some of Heinlein's lesser novels are quite good, and feature recurring characters.

Also, check out the Vorkosigan Saga by Bujold.
