An $$hp$$-adaptive pseudospectral method for solving optimal control problems. (English) Zbl 1266.49066
The authors propose an $$hp$$-adaptive pseudospectral method for solving optimal control problems. For the numerical solution of optimal control problems having nonsmooth solutions such a method is more suitable than the standard pseudospectral collocation method using globally defined polynomials of variable degree as trial functions. The numerical details of the author’s method are developed for an optimal control problem given in Bolza form. The results of various interesting numerical calculations, mainly taken from aerospace engineering, are presented. For the calculations a modified version of the open-source pseudospectral optimal control software GPOPS is used.
