Re: [Flightgear-devel] PI Simple Controller: Initial Integrator Value

[Josh D. <jos...@gm...>]

Sorry typo in my last reply, meant feedback if disabled it makes input go
to output when disabled, syncing it up, so that when it starts it goes from
where output is left off. But I don't want that, because then till start
the output at the error input which is bad.

Kind Regards,
