Optimal target aiming maneuver for an advanced aircraft via timescale pseudospectral method

A two-timescale Chebyshev pseudospectral optimal control method, which can reduce the converted nonlinear programming (NLP) significantly, is proposed. The optimal aiming maneuver problem of an advanced aircraft, which is a six-degree-of-freedom trajectory problem, is solved by this two-timescale method. It is the first time that the six-degree-of-freedom equations are used to solve optimization of the flight trajectory problems.
