摘要：In this note, we present an event-triggered robust adaptive control method with flexible prescribed performance for strict-feedback nonlinear systems. Unlike most existing event-triggered control results with only the inputs being triggered, here we introduce a triggering mechanism into the control law and the parameter estimator simultaneously, so that the communication resources are saved. It is worth noting that under the proposed triggering conditions, there are some challenges and difficu...

摘要：We present a novel framework for transferring the knowledge from one system (source) to design a stabilizing controller for a second system (target). Our motivation stems from the hypothesis that abundant data can be collected from the source system, whereas the data from the target system are scarce. We consider both cases where data collected from the source system is noiseless and noisy. For each case, by leveraging the data collected from the source system and a priori knowledge on the max...

摘要：This work studies a new notion of diagnosability called the pattern-pattern diagnosability in discrete event systems modeled by partially observable finite state automata. Suppose that in the system there are some sequences of events that are undesirable to happen, which we call the fault pattern. We want to determine whether the occurrence of the fault pattern can be determined before some sequences--which we call the critical pattern and may cause fatal consequences after the fault pattern-a...

摘要：This article explores the input saturation effect with nonidentical asymmetric levels in the multiagent consensus over a switching directed topology of weak connectivity. In particular, the saturation level for each agent is not symmetric, while the saturation levels associated with distinct agents are nonidentical. Both the continuous- and discrete-time cases are considered. For both the saturated multiagent systems, it is proven with the nonlinear contraction analysis that the conventional d...

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：In this article, we tackle the mean value control of a diatomic molecule. This problem is treated as a behavioral reachability problem. The control law is synthesized with an operator extracted from the characteristic polynomial of the system. This operator is applied to a Fourier series. The initial and final conditions are, respectively, adjusted with cosinus and sinus terms. We illustrate our results with an HCI molecule.

摘要：In the existing works on multiagent systems with neural-network-based protocols, it is usually assumed that states of all agents are within a compact set so that the approximation accuracy can be guaranteed. However, such an assumption means these protocols may only work if the agents' initial state values are set within a small enough neighborhood of the origin. This article develops a novel neural-network-based consensus protocol for a class of nonlinear multiagent systems. It is strictly pr...

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...
