摘 要：
Control parameterizationand direct collocation methods are known as the direct method for solvingoptimal control problems. The methods used for numerical integration anddifferentiation form different types of collocation methods. However, there isnot too much discussion on the numerical method for integration and differentiationwhen control parameterization method is used. Hence, it is difficult to make afair comparison between this two methods in terms of the solution accuracy aswell as the computational efficiency. In this talk, we propose a new hybridcomputational scheme for solving optimal control problems. The discretizationstrategy is adopted from control parameterization where only the controlfunction is discretized, however, the numerical integration and differentiationmethods is in line with those in existing direct collocation methods. Variousbenchmark examples are solved using the proposed method and conventional directcollocation methods, numerical results show that our new method is highlyeffective.
