摘要:This article considers control synthesis of an autonomous agent with linear temporal logic (LTL) specifications subject to environment and motion uncertainties. Specifically, the probabilistic motion of the agent is modeled by a Markov decision process (MDP) with unknown transition probabilities. The operating environment is assumed to be partially known, where the desired LTL specifications might be partially infeasible. A relaxed product MDP is constructed that allows the agent to revise its...

摘要:This article investigates the problem of global adaptive stabilization for discrete-time nonlinearly parameterized systems with nonaffine inputs. Using the notion of passivity and the idea of small bounded feedback, we present a discrete-time adaptive controller that globally adaptively stabilizes a class of non-affine systems with unknown parameters, under the assumptions that the unforced dynamics are stable and the controllabilitylike rank conditions hold. The latter is shown to be characte...

摘要:A system relying on the collective behavior of decision makers can be vulnerable to a variety of attacks. How well can a system operator protect performance in the face of these risks? We frame this question in the context of graphical coordination games, where the agents in a network choose between two conventions and derive benefits from coordinating neighbors, and system performance is measured in terms of the agents' welfare. In this article, we assess an operator's ability to mitigate two...

摘要:In this article, we study the distributed generalized Nash equilibrium (GNE) seeking problem of noncooperative games in dynamic environments. Each player in the game aims to minimize its own time-varying cost function subject to a local action set. The action sets of all players are coupled through a shared convex inequality constraint. Each player can only have access to its own cost function, its own set constraint, and a local block of the inequality constraint, and can only communicate wit...

摘要:Large-size populations consisting of a continuum of identical and noncooperative agents with stochastic dynamics are useful in modeling various biological and engineered systems. This article addresses the stochastic control problem of designing optimal state-feedback controllers that guarantee the closed-loop stability of the stationary density of such agents with nonlinear Langevin dynamics, under the action of their individual steady-state controls. We represent the corresponding coupled fo...

摘要:This article considers the finite-time adaptive control problem of nonlinear systems with quantized input signal. Compared with existing results, the quantized parameters are unknown and the bound of the disturbance is not required. By utilizing the command filter backstepping method, an adaptive switching-type controller is designed and a novel switching mechanism is also proposed. By regulating the controller parameters online, practical finite-time stability can be guaranteed for the closed...

摘要:In this article, we study the robust output regulation problem of linear systems by an event-triggered output feedback control law. We first summarize the solvability of the linear robust output regulation problem by the internal model design. Then, we implement this continuous-time control law by an event-triggered output feedback control law together with an output-based triggering mechanism. We show that, under almost the same solvability conditions as those for the linear robust output reg...

摘要:We present some new results on the dynamic regressor extension and mixing parameter estimators for linear regression models recently proposed in the literature. This technique has proven instrumental in the solution of several open problems in system identification and adaptive control. The new results include the following, first, a unified treatment of the continuous and the discrete-time cases; second, the proposal of two new extended regressor matrices, one which guarantees a quantifiable ...

摘要:A Boolean control network (BCN) is a discrete-time dynamical system whose variables take values from a binary set {0, 1}. At each time step, each variable of the BCN updates its value simultaneously according to a Boolean function which takes the state and control of the previous time step as its input. Given an ordered pair of states of a BCN, we define the set of reachable time steps as the set of positive integer k's where there exists a control sequence such that the BCN can be steered fro...

摘要:In this article, we propose a novel family of Lie algebra valued functions F-R on special orthogonal group SO(3). Each function belonging to this family induces a novel controller that stabilizes a rigid body attitude. All controllers induced by the family F-R form a controller class C-R. This novel controller class C-R contains both local and almost-global asymptotically stable controllers, and this article presents geometric stability results of the whole controller class C-R.
