Gradient Method for Solving Multisystem Integrated Optimal Control Problem With Undetermined Terminal Time

This article aims at proposing a multisystem gradient method (MSGM) for solving the integrated nonlinear optimal control problem with multiple systems and unspecified terminal time. This method is based on the influence functions, which are used to predict changes in performance indices and terminal conditions caused by changes in control and terminal time, so as to update the improvements of cont...
