Abstract :
Although longitudinal and lateral dynamics of helicopters in hovering are highly nonlinear and severely coupled, we will show in this paper that the nonlinear six degree-of-freedom H∞ controller designed for hovering helicopters can be exactly separated into two three degree-of-freedom controllers, one for translational motion and the other for rotational motion.
