Abstract: This paper proposes robust tracking performance criterion for flight control system clearance while other linear methods focus on robust stability criterion or stability margin criterion. The new criterion aims at guarantee of fast and accurate tracking of designated trajectory when flight control system suffers from uncertain parameters. With H_∞ theory, the clearance problem is transformed to a series of linear matrix inequalities on the vertices of parametric space. When the criterion is violated, two adaptive strategies are developed to identify the flyable region in parametric space. The proposed method is performed on a bank-to-turn missile as an example to illustrate the clearance process. Then the clearance result is validated by simulation.
