Abstract: The aerodynamic curve identification of aerial bomb from three-degree-of-freedom positional measurements is formulated as an optimal tracking control problem (OTCP). By using a spline parameterization of the drag coefficient curve that is taken as the control profile, the OTCP is converted into a parametric minimization problem where the proposed quasi-Newton-Raphson iteration is used to cut the computational cost. The inaccurate initial states can be corrected easily.
