Abstract

Dual Heuristic Programming (DHP) is a class of approximate dynamic programming methods using neural networks. Although there have been some successful applications of DHP, its performance and convergence are greatly influenced by the design of the step sizes in the critic module as well as the actor module. In this paper, a Delta-Bar-Delta learning rule is proposed for the DHP algorithm, which helps the two modules adjust learning rate individually and adaptively. Finally, the feasibility and effectiveness of the proposed method are illustrated in the learning control task of an inverted pendulum.
