Precise Path Tracking with Hierarchy-Structured Dynamic Inversion Approach
Jun’ichiro Kawaguchi,Yoshikazu Miyazawa,Tetsujiro Ninomiya 한국항공우주학회 2008 한국항공우주학회 학술발표회 논문집 Vol.- No.-
This paper proposes an automatic flight control methodology for precise path tracking problems with hierarchy-structured dynamic inversion approach, which is based on multiple time-scale separation and multiple loop closure method. The dynamic equations for aircraft are grouped into four categories according to the time-scale of the variables and the commanded reference response for the faster variables is generated using dynamic inversion. The methodology features simple and systematic flight control design for path tracking problems since the guidance law and the attitude control law are synthesized using the complete 6DOF nonlinear aircraft dynamics. It also features that the aircraft model and the hierarchical control structure are independent from each other so that it realizes a universal design of automatic flight controllers which utilize the vehicle's 6DOF simulation data on board. This paper in the first place shows the outline of the control law development using hierarchy-structured dynamic inversion approach and its application to path tracking problems in flight control design, which is finally followed by a 6DOF nonlinear night simulation in order to ensure the validity of the methodology.
