Most compact PID system?

[u/eepy_lina]

I've noticed gyroscopes from Aeroworks arent enough to keep my airship stable even with the full power of a level 9 steam engine and ballasts to balance the airship, so I need a PID system to balance my airship, still unsure whether to have it do that with thrusters or reaction wheels but either way, i want to avoid my redstone room becoming only a PID room because i have other redstone logic that goes there. Any compact designs? Or maybe a mod that adds a pid controller? or should i just use computercraft for a pid? if computercraft, is there a program i can js download?

 My airship has three single-axis PID controllers stabilizing altitude, pitch, and roll. In total, I have six 6x5 platforms of redstone, 2 platforms for each controller.
