摘要：The necessary and sufficient conditions for the newly introduced problem to find a strictly F-positive real (SF-PR) interpolant for a one-sided rational interpolation are given, as well as the set of all solutions. The SF-PR property of the interpolant H, for a rational matrix (RM) F to be found, implies that H is bistable and biproper (BiPS). Since such an interpolant is needed in the strong stabilization problem, the interpolation result is used to develop a control design algorithm such tha...

摘要：We propose a distributed control, in which many identical control agents are deployed for controlling a linear time-invariant plant that has multiple input-output channels. Each control agent can join or leave the control loop during the operation of stabilization without particular initialization over the whole networked agents. Once new control agents join the loop, they self-organize their control dynamics, which does not interfere the control by other active agents, which is achieved by lo...

摘要：Reference governors are add-on control schemes, which enforce state constraints on prestabilized systems by modifying, whenever necessary, the reference. This article studies the design schemes of reference governors for collisions-free leader-following coordination (CF-LFC) of nonlinear multiagent systems under unreliable communications. The unreliability is characterized as irregular topology switchings (e.g., due to communication failures, adversarial attacks, or other agents' blockages), w...

摘要：Secure state monitoring is mainly concerned with the problem of estimating the state of cyber-physical systems from a set of compromised attacked measurements. Compared with the case of fixed location attacks, a smart attacker who appropriately changes the attack target location can effectively resist intelligent defense detection and enhance the damage effect. To address this erratic attack, this article develops a distributed secure state monitoring protocol for a class of homogeneous cyber-...

摘要：This article is concerned with the high-performance control problem for the nonlinear systems in the sense of not only fast accurate reference tracking but also active damping of error oscillations caused by disturbances and unmodeled dynamics. A novel proportional-integral (PI) funnel control approach with rigorous theoretical insurance is put forward to handle this problem. In contrast with the existing solutions that work for weekly nonlinear systems or rely on available knowledge of the sy...

摘要：This article examines an online distributed optimization problem over an unbalanced digraph, in which a group of nodes in the network tries to collectively search for a minimizer of a time-varying global cost function while data are distributed among computing nodes. As the problem size becomes large, it will inevitably suffer from the communication bottleneck since each node that exchanges messages potentially transmits large amounts of information to its neighbors. To handle the issue, we de...

摘要：The article (Bazanella et al., 2019) presented the first results on generic identifiability of dynamic networks with partial excitation and partial measurements. All previous papers assumed that either all nodes are excited or all nodes are measured. One key contribution of that paper was to establish a set of necessary conditions on the excitation and measurement pattern (EMP) that guarantee generic identifiability: all sources must be excited and all sinks measured, and all other nodes must ...

摘要：This work is concerned with the feedback stabilization of a class of semilinear system with distributed delay. We consider an observation condition in terms of the semigroup solution of the linear part of the considered system and parameterized by a positive constant. Some sufficient conditions are given with respect to this parameter and the bounded feedback control to guarantee the feedback stabilization of the semilinear system with distributed delay. Moreover, when this parameter is greate...

摘要：The problem of stabilizing a class of nonholonomic systems in a chained form affected by both matched and unmatched uncertainties is addressed in this article. The proposed design methodology is based on a discontinuous transformation of the perturbed nonholonomic system to which an adaptive multiple-surface sliding mode technique is applied. The generation of a sliding mode allows to eliminate the effect of matched uncertainties, while a suitable function approximation technique enables to de...

摘要：Overactuated systems often make it possible to achieve specific performances by switching between different subsets of actuators. However, when the system parameters are unknown, transferring authority to different subsets of actuators is challenging due to stability and performance efficiency concerns. This article presents an efficient algorithm to tackle the so-called learn and control while switching between different actuating modes problem in the linear quadratic setting. Our proposed st...
