摘要：This article explores the distributed leader-following consensus control problem of nonlinear multiagent systems subject to stochastic output sensing noises under a fixed directed topology. Different from existing research, we pay attention to the effect of multiplicative stochastic noises on the sensors, and the noise intensity can be described as an unknown time-varying function with an arbitrarily large bound. In this condition, we put forward the noise intensity classification-based distri...

摘要：This study addresses the deficiencies in the assumptions of the results in (Chen and Yang, 2017) due to the lack of uniformity. We first show the missing hypothesis by presenting a counterexample. Then, we prove why they are wrong in that form and show the errors in the proof of the main result of (Chen and Yang, 2017). Next, we compare the assumptions and related results of (Chen and Yang, 2017) with similar works in the literature. Lastly, we give suggestions to complement the shortcomings o...

摘要：This article solves the problem of prescribed-time (PT) prescribed-performance tracking for a class of nonlinear systems with nonvanishing uncertainties based on a finite-time command filter (FTCF). To deal with nonvanishing uncertainties, a novel PT stabilization criterion that incorporates an adaptive method is proposed and a compensation mechanism is established to reduce the errors caused by FTCF, where the parameter adaptive estimation error achieves asymptotically zero convergence. Based...

摘要：The aim of this article is to design static output feedback controllers for multi-input-multi-output (MIMO) linear time-invariant (LTI) systems, with the requirements of positivity and asymptotic stability to be guaranteed in closed-loop systems. By expressing the matrix product $KC$ as a sum of rank one matrices, new necessary and sufficient conditions for the existence of a static output feedback controller are derived in terms of linear programming (LP) conditions. One of the advantages of ...

摘要：This study addresses the intricate challenge of decentralized output-feedback control for stochastic non-triangular nonlinear interconnected systems with unknown time-varying sensor sensitivity in a dynamic event-triggered context. The presence of stochastic disturbances, non-triangular structural uncertainties, and evolving sensor sensitivity distinguishes this problem of global asymptotic stability from conventional event-triggered control scenarios. Existing event-triggered control approach...

摘要：This article studies the security issue of malicious attackers degrading remote estimation by injecting false data into sensors in cyber-physical systems. The typical attacks involve initially proposing a parameterized pattern, such as a linear one, then optimizing parameters according to system performance. The parameterized model limits the destructivity because it cannot cover all patterns. To overcome this, we investigate a generalized deception attack model with an unparameterized form. T...

摘要：Networked multiagent systems often communicate information over low-power shared wireless networks in unlicensed spectrum, which are prone to denial-of-service attacks. An instance of this scenario is considered: multiple pairs of agents, each pair consisting of a transmitting sensor and a receiver acting as an estimator, communicate strategically over shared communication networks in the presence of a jammer who may launch a denial-of-service attack in the form of packet collisions. Using the...

摘要：The linear programming (LP) approach is, together with value iteration and policy iteration, one of the three fundamental methods to solve optimal control problems in a dynamic programming setting. Despite its simple formulation, versatility, and predisposition to be employed in model-free settings, the LP approach has not enjoyed the same popularity as the other methods. The reason is the often poor scalability of the exact LP approach and the difficulty to obtain bounded solutions for a reas...

摘要：This article studies a multiplayer reach-avoid differential game in the presence of general polygonal obstacles that block the players' motions. The pursuers cooperate to protect a convex region from the evaders who try to reach the region. We propose a multiplayer onsite and close-to-goal (MOCG) pursuit strategy that can tell and achieve an increasing lower bound on the number of guaranteed defeated evaders. This pursuit strategy fuses the subgame outcomes for multiple pursuers against one ev...

摘要：We investigate discrete-time mean-variance portfolio selection problems viewed as a Markov decision process. We transform the problems into a new model with a deterministic transition function for which the optimality equation holds. In this way, we can solve the problem recursively and obtain a time-consistent solution, which is an optimal solution that meets the Bellman optimality principle. We apply our technique for solving explicitly a more general framework.
