摘要：In this article, we study the optimal control of systems subject to input-varying hydraulic delays, i.e., systems where the delay on the input depends on the past values of the input through a specific integral relation. The calculus of variations of this problem reveals its nondifferentiable nature. Then, a smooth relaxation is proposed to derive an iterative optimization algorithm. A convergence proof is detailed. The practical interest of the algorithm is evidenced on a numerical example.

摘要：This article focuses on the formation control problem of nonlinear multiagent systems under denial-of-service attacks. The formation control can be preserved by the distributed hybrid event-triggering strategies (HETSs). As a balance between periodic and continuous event-triggering strategies, HETS arranges a tradeoff between the resource utilization and the communication frequency among agents. Theoretical results are verified using a benchmark problem of six miniature quadrotor prototypes.
