Outline of Final Research Achievements

The aim of this study is to develop practical automatic control systems for a underactuated airship, which is described by a set of nonlinear equations. One of our main results is to present new optimal control systems for the airship based on practical tracking control method. By introducing an allowable tracking error to the airship system, the tracking control problem of the nonlinear system can be reduced to that of a simple linear system. This approach makes the well-known linear control theory applicable in the control design. Therefore, optimal tracking controllers for the airship system are proposed with robustness against disturbance and noise. Some flight simulations and experiments have been performed and the effectiveness of the proposed control systems has been demonstrated.
