1997年12月1日 · In this paper we study the convergence of the Galerkin approximation method applied to the generalized Hamilton-Jacobi-Bellman (GHJB) equation over a compact set containing the origin. The GHJB equation gives the cost of an arbitrary control law and can be used to improve the performance of this control.
Simpler near-optimal controllers through direct supervision
2009年8月20日 · I show how to obtain these signals, using the GHJB equation to calculate one component of grad-J (x) -- the one parallel with dx/dt -- and computing all the other components by backward-in-time integration, using a formula similar to the Euler-Lagrange equation. I then compare this direct algorithm with GHJB on 2 test problems.
An iterative method for optimal feedback control and generalized HJB ...
2017年12月4日 · In this paper, a new iterative method is proposed to solve the generalized Hamilton-Jacobi-Bellman ( GHJB ) equation through successively approximate it. Firstly, the GHJB equation is converted to an algebraic equation with the vector norm, which is essentially a set of simultaneous nonlinear equations in the case of dynamic systems.

Hamilton-Jacobi-Bellman (HJB) 方程 - CSDN博客
2024年5月6日 · HJB方程提供了求解 动态规划 问题的一个有效工具,尤其是在连续时间、连续状态空间的环境中。 其基本思想是将原问题转化为寻找一个价值函数(也称作代价函数或泛函),该函数表示从当前状态出发到某个终止条件下的最优成本或收益。 HJB方程确保了这个价值函数满足一定的动态一致性条件。 对于一个标准的连续时间最优控制问题,其基本要素包括: X \mathcal {X} X。 U \mathcal {U} U。 f : X × U × R → X f: \mathcal {X} \times \mathcal {U} \times …
Generalized Hamilton–Jacobi–Bellman Formulation ... - IEEE Xplore
In this paper, we consider the use of nonlinear networks towards obtaining nearly optimal solutions to the control of nonlinear discrete-time (DT) systems. The method is based on least squares successive approximation solution of the generalized Hamilton–Jacobi–Bellman (GHJB) equation which appears in optimization problems.
Policy iteration for Hamilton–Jacobi–Bellman equations
2021年4月24日 · Policy iteration is a widely used technique to solve the Hamilton Jacobi Bellman (HJB) equation, which arises from nonlinear optimal feedback control theory. Its convergence analysis has attracted much attention in the unconstrained case.
