Despite the variety of methods available to solve nonlinear optimal con-trol problems,
numerical methods are still evolving to solve these problems. This paper deals with the …

Most existing necessary conditions for optimal control based on adjoining methods require
both state information and costate information, yet the lack of costates for a given feasible …

We consider system identification for nonlinear, non-autonomous systems of ordinary
differential equations. To estimate parameters and states from noisy observations, we …

In this paper, we study linear quadratic regulator (LQR) design subject to linear equality
constraints in the controller parameters. Necessary solvability conditions are provided, and a …

In the sparsely populated areas without electricity, the hydro photovoltaic power station is a
