A probabilistic quantization mechanism is introduced to handle the raw measurement signals for the purpose of facilitating digital communication over network. Certain transmission models are proposed to describe the behaviors under the effects of multi-rate dynamics, probabilistic quantization and limited transmission power. A delicately designed FFB fusion scheme is proposed to acquire the desired state estimates, where the local filters will receive feedback from the fusion center to reset their estimates. The parameters for the local filters are calculated by recursively minimizing their upper-bounds for the estimation error covariances. Furthermore, new conditions have been derived to analyze the ultimately boundedness of the estimation error covariance for the fusion center. Subsequently, a power allocation strategy is designed by minimizing such ultimate bound subject to the given transmission power constraint.

Firstly, a novel zonotopic state observer is designed to obtain point-valued estimations for the considered system. To improve estimation accuracy, a decoupling method is simultaneously proposed to separate the disturbance from the error dynamics. Secondly, the discrete-time linear systems subjected to intermittent nonperiodic DoS attacks are restructured into a class of augmented switched systems, which comprises both a stable subsystem and an unstable subsystem. To guarantee the stability of the augmented system, a switching law is designed, which solves the instability problem of system under long-term or high-frequency DoS attacks.

A co-design strategy of control barrier functions (CBFs) and barrier Lyapunov functions (BLFs) is proposed, which inherits the robustness and stability of traditional adaptive backstepping controllers. First, a safe virtual control signal is generated by the CBF-induced quadratic programming (QP), which is the suboptimal and smooth solution of the QP with a shifting function. Then, a BLF-based backstepping controller is designed by following the safe virtual control signal. It is shown that the co-design can minimize the damage to the original tracking performance on the premise of safety guarantees. The distinguishing point of the safety design over the existing results is to avoid constructing the high-order CBFs that lead to conservative feasible sets of inputs for ensuring high-relative-degree safety constraints.

Besides, nearly all of related results cannot guarantee local constraints to be satisfied all the time, because physical players cannot control their decisions directly due to system dynamics. Here we develop a distributed adaptive strategy on the basis of gradient descent, projection operators, primal–dual methods and state feedback. The strategy is fully distributed. We analyze the strategy via variational analysis and Lyapunov theory.
