Abstract :
In allusion to the control problem of the complex stochastic largescale system, a novel decentralized control method based on information fusion estimation is proposed in this paper. Based on the information fusion optimal estimation theorem, by fusing the one-step predictive information of the largescale system state and the sub-system measurement information, the optimal estimation of the largescale system state is derived. Moreover, by fusing the state estimation information, the co-state estimation information and the soft constrained control energy information, the optimal estimation of the control station output is obtained.
