The paper addresses the decentralized optimal con-trol and stabilization problems for interconnected systems sub-ject to asymmetric information.Compared with previous work,a closed-loop optimal solution to the control problem and sufficient and necessary conditions for the stabilization problem of the interconnected systems are given for the first time.The main challenge lies in three aspects:Firstly,the asymmetric informa-tion results in coupling between control and estimation and fail-ure of the separation principle.Secondly,two extra unknown variables are generated by asymmetric information(different information filtration)when solving forward-backward stochas-tic difference equations.Thirdly,the existence of additive noise makes the study of mean-square boundedness an obstacle.The adopted technique is proving and assuming the linear form of controllers and establishing the equivalence between the two sys-tems with and without additive noise.A dual-motor parallel drive system is presented to demonstrate the validity of the proposed algorithm.
