WebA method of this type may succeed in constructing a \good" approximation of the value function, yet lack reliable guarantees in terms of near-optimality of the resulting policy. Actor-critic methods aim at combining the strong points of actor-only and critic-only methods, by incorporating value function approximation in the policy gradient methods. WebJul 12, 2016 · Model-free control is an important and promising topic in control fields, which has attracted extensive attention in the past few years. In this paper, we aim to solve the model-free optimal tracking control problem of nonaffine nonlinear discrete-time systems. A critic-only Q-learning (CoQL) method is developed, which learns the optimal tracking …
