| Abstract: | The direct optimization using collocation based on high order Gauss Lobatto Quadrature rules was discussed.It is a high accuracy and small calculation method.Presently,relative low order rules from the Guass Lobatto rules,such as the trapezoid and Simpson method,were used to construct collocation solution schemes.The advantages of high order scheme are more accuracy and less subintervals which make calculation more quickly.Trajectory optimizations were calculated and several key problems were discussed |
