This paper presents simulation models and control laws for the autonomous helicopter Skeldar. The simulation models include rotor dynamics, flight mechanics and the coupling between these equations and the rotor mechanism. The feedback control laws are based on linear quadratic control design which gives the control good robustness properties.
