Computational Optimal Impact Angle Control Guidance Laws Weighted by Arbitrary Functions

This paper presents a computational impact angle control guidance law based on the energy cost weighted by arbitrary functions in order to shape acceleration command as desired. The optimal problem is established frame and solved Gauss orthogonal collocation method. proposed formulated from generalized framework, thus new that allows achieving specific goal can be easily obtained way of devising proper weighting function (smooth, piecewise, nonsmooth, or even discontinuous). property provides more degrees freedom design accomplish specified objective. A hardware experiment conducted evaluate real-time capacity law. Illustrative examples with several types functions, including smooth, discontinuous are provided demonstrate advantages
