摘要：This article investigates the relationship between realization and observability of Boolean control networks (BCNs) and gives some invariants under minimum realization (MR), such as, decoupling, invertibility, etc. It is proved that the MR of a BCN exists uniquely up to coordinate transformations and a BCN is an MR of itself if and only if it is weakly observable. Based on these, the MR of a given BCN can be constructed. Moreover, the observability decomposition of BCNs is discussed and an equ...

摘要：In a recent work, we introduced a new set of problems in the area of networked multiple mobile robotic systems that concern the time-optimal execution of certain coverage tasks taking place in constricted environments. That work provided the detailed problem definitions, positioned these problems in the context of the corresponding literature, formulated them as mixed integer programs (MIPs), and established their NP-hardness. This article introduces a strong combinatorial relaxation for these...

摘要：The article deals with synthesis of observers for a linearized water wave system (LWWS) confined in a bounded rectangular fluid domain. To estimate the state of LWWS, including velocity potential and wave elevation, infinite-dimensional state observers are designed by using two different observation measurements. The first observer is designed by measuring the distributed free-surface wave elevation. The convergence rate of this observer is proved to be exponential and fast. The second observe...

摘要：In this article, we initiate an important class of vertex-marked directed graphs, referred to as the strong structurally observable graphs (SSOGs), to be the fundamental structural architectures ensuring the observability of several prevalent types of discrete-time iteration systems. This article also answers the minimal control node problem of SSOGs by carrying out two explicit formulas and the corresponding polynomial-time algorithms. Primitively, by exploring the strong structural observabi...

摘要：This article deals with the trajectory tracking problem of a class of switched systems, whose dynamic matrixes are periodic with respect to a parameter theta that can be a time- or state-dependent function. The design conditions are expressed in terms of LMIs and ensure asymptotic tracking of a prespecified trajectory along with a guaranteed cost of performance. Two three-phase electrical systems are used for motivation and to validate the proposed theory: an ac-dc power converter and a perman...

摘要：This paper studies the problem of integrated distributed network localization and formation maneuver control. We develop an integrated relative-measurement-based scheme, which only uses relative positions, distances, bearings, angles, ratio-of-distances, or their combination to achieve distributed network localization and formation maneuver control in R-d(d >= 2). By exploring the localizability and invariance of the target formation, the scale, rotation, and translation of the formation can b...

摘要：In this article, the state-flipped control technique is explored to investigate the stabilization of probabilistic Boolean networks (PBNs). Changing the values of many nodes from 0 to 1 (or from 1 to 0) is called the state-flipped control. The concepts of fixed point, reachable sets, and finite-time global stabilization of PBNs under state-flipped control are proposed. Several necessary and sufficient conditions for global stabilization are also derived based on the reachable sets of a given s...

摘要：An important objective in the design of feedback control systems is the pattern generation. The term pattern denotes the behavior of the individual plant states relative to one another in steady state, e.g., periodic with a specified frequency and phase offset. Here, we solve the optimal, linear, output feedback problem in which the controller is autonomous, achieves pattern generation, and minimizes the $L_{2}$ norm of the transient portion of the impulse response. Our result reveals the opti...

摘要：A stochastic, hybrid algorithm for global almost sure unanimous decision making in multiagent systems is introduced. Homogeneous agents communicate over an undirected connected graph to make a unanimous selection among a finite set of decision states. The agents have inertia corresponding to stable, linear, and continuous-time dynamics. The algorithm equips each agent with a logic variable and designs logic-variable reset rules to ensure eventual unanimity. These resets occur randomly in time....

摘要：This article describes an extension of the well-known model reference adaptive control (MRAC) approach. The extension relies on explicitly involving the tracking error in the feedback control law: it is shown that including this term along with its appropriate extra adaptive gain allows one to handle possibly unstable reference dynamics. Owing to its stabilizing nature, the proposed framework is referred to as model reference adaptive stabilizing control. Such an extension turns out to be part...
