Zero-Lag Vertical Stabilizer

Thanks to the space update, it is now possible to replicate how real stabilizer systems achieve accurate movement.

Installation guide:

The moving parts must be mounting on a VELOCITY pivot with NO POWER. This makes it behave as a free moving hinge. infinite electricity will make this not work.

Place the reaction wheel sideways with the positive arrow going up

Make sure the tilt sensor is on the same subgrid as the moving parts

Counterweights aren't needed, but it reduces the saturation from trimming out excess forces.


Enable the option "Suspend Control" to let the assembly move under it's own weight.
Adjust the trim in the controller to make the gun naturally balanced on the pivot.
Disable "Suspend Control" to return assembly to controlled behavior

The best performance I've gotten was using sticky 10% sensitivity. It should work with slower movement fine but if you want to increase sensitivity you may need to adjust the PID or it can overshoot.
