... Coupling characteristics Unmanned helicopter Hardware in the loop Internal dynamics and external disturbances The field of unmanned helicopter (UH) is under active research. This is because autonomous UH can replace humans in situations where missions are dangerous, expensive or impossible. Only...

... flight test yet, as all the tests are conducted in the numerical simulation and simulation with a hardware-in-the-loop (HIL) platform. Social implications The designed flight control strategy can solve the common problem of coupling characteristics between channels for coaxial UH, and it has...
