摘      要：Aiming at the time-optimal control problem of hypersonic vehicles(HSV)in ascending stage,a trigonometric regularization method(TRM)is introduced based on the indirect method of optimal *** method avoids analyzing the switching function and distinguishing between singular control and bang-bang control,where the singular control problem is more *** in bang-bang control,the costate variables are unsmooth due to the control jumping,resulting in difficulty in solving the two-point boundary value problem(TPBVP)induced by the indirect *** at the easy divergence when solving the TPBVP,the continuation method is *** method uses the solution of the simplified problem as the initial value of the *** through solving a series of TPBVP,it approximates to the solution of the original complex *** calculation results show that through the above two methods,the time-optimal control problem of HSV in ascending stage under the complex model can be solved conveniently.
