Adaptive Dynamic Programming - A New Tool for Intelligent Control
Abstract:
Adaptive Dynamic Programming (ADP) has received increasing attentionrecently. ADP scheme is a design that approximates dynamic programmingin the general case, i.e., approximates optimal control over time innoisy, nonlinear environments. There are many engineering problems inpractice which can be formulated as cost maximization or minimizationproblems. Dynamic programming is a very useful tool in solving theseproblems. However, it is often computationally untenable to rundynamic programming due to the backward numerical process required forits solutions. Over the years, progress has been made to provideapproximate solutions to dynamic programming. The idea is toapproximate dynamic programming solutions by using neural networks toapproximate the cost function. The methodology is a very useful toolfor building intelligent agents/controllers in almost any environment.This talk will review the theoretical development of ADP. Detailsabout the training of the neural networks used in the present designwill also be presented. The pole balancing (inverted pendulum) problemwill be used as the benchmark in this presentation to show theapplicability of ADP.
