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.

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.

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.

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.

庞特金最大值原理弥补了这一缺陷，算是对变分法的延伸；动态规划主要用 贝尔曼最优原理，也就是我们之前讲述的H-J-B方程。 在上一篇文章我曾经对于如何求解无解析解的偏微分方程提出了疑问，后来发现 郭老师 的书里就有现成的解答。 书中提供了三种解决思路：将值函数离散化，求解数值解，然后用 贪婪算法 得到最优控制；利用变分法，将微分方程转化成变分代数方程，在标称轨迹展开，得到微分动态规划DDP;函数逼近理论，对方程中的 回报函数 和控制函数进行函数 …

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.

哈密顿-雅可比-贝尔曼方程（Hamilton-Jacobi-Bellman equation，简称HJB方程）是一个偏微分方程，是最优控制的核心。 HJB方程式的解是针对特定动态系统及相关代价函数下，有最小代价的实值函数。
