摘要：While distributed parameter estimation has been extensively studied in the literature, little has been achieved in terms of robust analysis and tuning methods in the presence of disturbances. However, disturbances, such as measurement noise and model mismatches occur in any real-world setting. Therefore, providing tuning methods with specific robustness guarantees would greatly benefit the practical application. To address these issues, we recast the error dynamics of a continuous-time version...

摘要：Recently, the concept of $\mathit {k}$-contraction has been introduced as a promising generalization of contraction for dynamical systems. However, the study of $\mathit {k}$-contraction properties has faced significant challenges due to the reliance on complex mathematical objects called matrix compounds. As a result, related control design methodologies have yet to appear in the literature. In this article, we overcome existing limitations and propose new sufficient conditions for $\mathit {...

摘要：This article is concerned with the issue of distributed hierarchical secure estimation over wireless cluster networks under denial-of-service (DoS) attacks. Here, communication interactions rely on hierarchical networks with local wireless sensor networks in the first layer and wireless cluster networks in the second layer. To reduce communication consumption over local wireless sensor networks, recursive event-triggered sequential local estimators are first proposed in each cluster head (CH) ...

摘要：This article presents a generic design approach to the adaptive event-triggered control for a class of nonlinear systems subject to nonlinearly appearing unknown parameters and uncertain nonlinearities. The overall event-triggered control strategy relies on the co-design consisting of parameterized control laws, a parameter switching logic, and an event-triggered sampling mechanism, which guarantees that all the closed-loop states are bounded and the plant state asymptotically converges to the...

摘要：This article studies the adaptive control problem for a class of uncertain strict-feedback nonlinear systems, where both tracking error and full states need to be directly constrained. First, a novel universal constraint approach is introduced, which combines a universal composite barrier function that depends on the tracking error and the output, with universal barrier functions that depend on the remaining states. Compared with existing research, it displays the following appealing features....
