Difficulty: Hard
This problem was adapted from Example 6.3 from [1]. This example is available via the link on the right.
The implementation of this examples will not be explained in details due to similarity with other examples. Please refer to an example with similar complexity for implementation instructions, or other examples in the list of examples with Detailed Instructions.
Results from ICLOCS2
Using the Hermite-Simpson discretization scheme of ICLOCS2, the following state and input trajectories are obtained under a mesh refinement scheme starting with 30 mesh points. The computation time with IPOPT (NLP convergence tol set to 1e-09) is about 11 seconds after 1 mesh refinement iteration, using finite difference derivative calculations on an Intel i7-6700 desktop computer.
