摘要：Herein, we investigate the asymptotical controllability of continuous-time probabilistic logic control systems (CT-PLCSs) under piecewise constant and right continuous controls (PCRCCs). The theory of an invariant subset for a CT-PLCS controlled by a PCRCC is developed. Based on this theory, we prove that a state is asymptotically reachable from another state under a PCRCC if and only if it is asymptotically reachable under a simple periodic PCRCC; in other words, the control values are pairwi...

摘要：Control barrier functions (CBFs) ensure the safety of controlled dynamical systems by enforcing forward invariance of safe subsets of the state space. First-order CBFs are applicable for systems where the control input appears in the first time derivative of the controlled output. High-order CBFs (HOCBFs) extend the notion of CBFs to systems of any order, following a procedure reminiscent of the recursive design of a control Lyapunov function in backstepping. Asymptotic stability of compact sa...

摘要：This article is concerned with the distributed online saddle point problem for multiagent networks over time-varying graphs. The objective is to design distributed online algorithms for optimizing the accumulation of the time-varying loss functions, and further to analyze the efficiency of the algorithms by utilizing the so-called dynamic regret as a performance measure. To this end, two kinds of distributed online optimization algorithms are developed by considering full-information feedback ...

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：Game theory is playing more and more important roles in understanding complex systems and in investigating intelligent machines with various uncertainties. As a starting point, we consider the classical two-player zero-sum linear-quadratic stochastic differential games, but in contrast to most of the existing studies, the coefficient matrices of the systems are assumed to be unknown to both players, and consequently it is necessary to study adaptive strategies of the players, which may be term...

摘要：Existing approaches to robust global asymptotic stabilization of a pair of antipodal points on unit n-sphere S-n typically involve the noncentrally synergistic hybrid controllers for attitude tracking on unit quaternion space. However, when switching faults occur due to parameter errors, the noncentrally synergistic property can lead to the unwinding problem or, in some cases, destabilize the desired set. In this work, a hybrid controller is first proposed based on a novel centrally synergisti...

摘要：This study is concerned with the bumpless transfer control (BTC) for discrete-time Markov jump linear systems (MJLSs) subject to constraints on states and inputs. A new approach called bumpless transfer model predictive control (BT-MPC) is proposed, which simultaneously optimizes the stabilization performance and bumpless transfer performance in a receding horizon manner. By a scenario-based control law, the fixed-duration transition progress is generalized to the mutable-duration one, so that...
