Abstract: | In this paper, a method is proposed to solve free endpoint optimal control problems with linear state and quadratic cost. After translating the problem into a two-point boundary-value problem (TPBVP) that arises from the optimization of the Hamiltonian, two pointst1 andt2,t1<t2, belonging to the given interval of integration [t0,tf], are chosen and conditions are derived at these points appropriately. Then, letting =(t–t0)/, =(tf–t)/, the -scaled, the original, and the -scaled TPBVP's are solved on the intervals [t0,t1], [t1,t2], and [t2,tf] respectively as boundary-value problems.The authors are deeply indebted to Dr. S. M. Roberts for his valuable comments and suggestions, which improved the clarity of the paper. |
