Unmanned helicopters pose a challenge to nonlinear control design and development. Unmanned helicopters are inherently unstable without closed loop control, setting it apart from many other classes of mechanical systems that possess desirable structural properties such as passivity or dissipativity. In addition, helicopter dynamics are highly nonlinear and strongly coupled, and therefore dis…
