WebHamiltonian systems and optimal control. Part of the NATO Science for Peace and Security Series book series (NAPSB) Solutions of any optimal control problem are described by trajectories of a Hamiltonian system. The system is intrinsically associated to the problem by a procedure that is a geometric elaboration of the Lagrange multipliers rule. WebAug 1, 2024 · The Hamiltonian and Optimality System. The optimal control must satisfy the necessary conditions that are formulated by Pontryagin’s maximum principle ... Optimal control theory was used to establish conditions under which the spread of corruption can be stopped and to examine the impact of a possible combination of these two controls on …

WebNov 11, 2024 · In this paper, we combine two main topics in mechanics and optimal control theory: contact Hamiltonian systems and Pontryagin maximum principle. As an important result, among others, we develop a contact Pontryagin maximum principle that permits to deal with optimal control problems with dissipation. WebOptimal control theory is a branch of mathematical optimization that deals with finding a control for a dynamical system over a period of time such that an objective function is optimized. It has numerous applications in science, engineering and operations research. For example, the dynamical system might be a spacecraft with controls corresponding to …
WebThe optimal control problem is solved using a Hamiltonian that reads: H = v(k,c,t)+µ(t)g(k,c,t) (1) µ(t) is the multiplier on the equation of motion. In a classical growth … WebThe natural Hamiltonian function in optimal control is generally not differentiable. However, it is possible to use the theory of generalized gradients (which we discuss as a …
In optimal control theory, the Hamilton-Jacobi-Bellman (HJB) equation gives a necessary and sufficient condition for optimality of a control with respect to a loss function. It is, in general, a nonlinear partial differential equation in the value function, which means its solution is the value function itself. Once this solution is known, it can be used to obtain the optimal control by taking the maximizer (or minimizer) of the Hamiltonian involved in the HJB equation. WebOptimal Control Theory is a modern approach to the dynamic optimization without being constrained to Interior Solutions, nonetheless it still relies on di erentiability. The …
The Hamiltonian is a function used to solve a problem of optimal control for a dynamical system. It can be understood as an instantaneous increment of the Lagrangian expression of the problem that is to be optimized over a certain time period.
