Robust Adaptive Dynamic Programming for Large-Scale Systems With an Application to Multimachine Power Systems
Yu Jiang, Zhong‐Ping Jiang · IEEE Transactions on Circuits & Systems II Express Briefs · 2012
This brief presents a new approach to decentralized control design of complex systems with unknown parameters and dynamic uncertainties. A key strategy is to use the theory of robust adaptive dynamic programming and the policy iteration technique. An iterative control algorithm is given to devise a decentralized optimal controller that globally asymptotically stabilizes the system in question. Stability analysis is accomplished by means of the small-gain theorem. The effectiveness of the proposed computational control algorithm is demonstrated via the online learning control of multimachine power systems with governor controllers.
