The idea of the method is a direct application of the Q-learning adaptive dynamic programming for time-varying systems. In order to derive the optimal control policy, an actor-critic structure is constructed and the time-varying least square method is adopted for parameter adaptation. The derived control policy robustly stabilizes the time-varying system and guarantees an optimal control performance. As no particular system information is required throughout the process, the proposed method provides a feasible solution to a large variety of applications. The validity of the proposed method is verified through simulation studies. © 2013 IEEE.||Source Title:||Proceedings of the 2013 IEEE Conference on Cybernetics and Intelligent Systems, CIS 2013||URI:||http://scholarbank.nus.edu.sg/handle/10635/83440||DOI:||10.1109/ICCIS.2013.6751580|
