Variable stability flight control is one of the key techniques in helicopter flight simulation. Main difficulties in variable stability flight controller design are attributable to aerodynamic parameter uncertainties. A strong tracking adaptive controller with double target helicopter models is presented for variable stability helicopter, which has significant advantages of separating strong tracking feedback compensation facility from parameters design of adaptive control, and the system stability margin is improved in process of adjustable parameter correction and tracking error is reduced remarkably. Simulation results show the effectiveness and feasibility of the proposed method.
