Abstract：This article considers the secure state estimation and control for the heterogeneous interconnected systems under node-injected attacks,and a finite-time adaptive dynamic programming based on the distributed secure remote estima-tion is designed to improve the security of the control systems.Firstly,to recover the state information of the heterogeneous interconnected systems under the node-injected attacks,the distributed remote secure estimator is designed based on the unscented Kalman filter and the optimal attack compensation strategy.Then,by combining the optimal objective of the secure estimation and the optimal objective of the consensus,the distributed secure optimal control strategy is presented based on the solution of the Hamilton equation.Furthermore,to approximate the optimal controller and value function in the finite-time,the finite-time tuning laws of the critic-actor network are proposed based on the policy iteration algorithm and finite-time optimization.Finally,the effectiveness of the proposed method is verified by the comparison result analysis.
