摘要:This article addresses controller synthesis for unknown multi-input-multioutput systems to satisfy temporal reach-avoid-stay (T-RAS) specifications using spatiotemporal tubes (STTs). To design a valid STT, the tube constraints are first formulated as a Robust Optimization Program and then relaxed through a sampling-based scenario optimization program. Subsequently, an approximation-free, closed-form controller is designed to satisfy the T-RAS specification. Finally, the approach is validated o...

摘要:In this article, we propose a new framework of Markov alpha-potential games to study Markov games. We show that any Markov game with finite state and finite action is a Markov alpha-potential game and establish the existence of an associated alpha-potential function. Any optimizer of an alpha-potential function is shown to be an alpha-stationary Nash equilibrium. We study two important classes of practically significant Markov games, Markov congestion games and the perturbed Markov team games,...

摘要:This article presents a novel robust predictive controller for constrained nonlinear systems that is able to track piecewise constant setpoint signals. The tracking model predictive controller presented in this article extends the nonlinear MPC for tracking to the more complex case of nonlinear systems subject to bounded and not necessarily additive perturbations. The optimal control problem that is solved at each step penalizes the deviation of the predicted nominal system trajectory from an ...

摘要:This technical note introduces a novel design approach to address the leader-following consensus problem in linear multiagent systems (MASs) through distributed impulsive control. First, robust stability criteria are established for a class of linear impulsive systems with parameteric input matrix. These criteria are then applied to the design of the distributed impulsive controller. The proposed design approach decouples the design of the impulsive control gains from the detailed graph proper...

摘要:In this article, we present two novel approaches to accelerate the convergence of a class of Markov decision problems with stationary state space components, which iterate on reduced state and action spaces and converge to an optimal policy. The time aggregation-based algorithm partitions the state space into disjoint sets, one for each possible combination of the nonstationary components, and iterates in the sets. The local search policy set iteration algorithm introduces a novel modified pol...

摘要:In this article, we present new families of algorithms for the repeated play of two-agent (near) zero-sum games and two-agent zero-sum stochastic games. For example, the family includes fictitious play and its variants as members. Commonly, the algorithms in this family are all uncoupled, rational, and convergent even in heterogeneous cases, e.g., where the dynamics may differ in terms of learning rates, full, none or temporal access to opponent actions, and model-based versus model-free learn...

摘要:Applying machine learning methods to physical systems that are supposed to act in the real world requires providing safety guarantees. However, methods that include such guarantees often come at a high computational cost, making them inapplicable to large datasets and embedded devices with low computational power. In this article, we propose CoLSafe, a computationally lightweight safe learning algorithm whose computational complexity grows sublinearly with the number of data points. We derive ...

摘要:In this article, we introduce a new concept of modal strong structural controllability in linear time-invariant (LTI) systems. An eigenvalue of a system matrix is considered controllable if it can be directly influenced by the control inputs. We focus on an arbitrary set Delta subset of C and define a specific family of systems as modal strongly structurally controllable with respect to Delta if, for all systems in this family, every lambda is an element of Delta is a controllable eigenvalue. ...

摘要:In this technical note, we introduce a novel approach to studying consensus of continuous-time nonlinear systems with varying topology based on the Hilbert metric. We demonstrate that this metric offers significant flexibility in analyzing consensus properties, while effectively handling nonlinearities and time dependencies. Notably, our approach relaxes key technical assumptions from some standard results while yielding stronger conclusions with shorter proofs. This framework provides new ins...

摘要:This manuscript shows the global exponential stability preservation for the class of fully nonlinear retarded globally Lipschitz systems with time-varying delays under suitably fast sampling while considering at the same time the problem of the nonavailability in the buffer device of the system variables at some past (delayed) times. To this aim, a spline interpolation scheme is exploited to derive the digital control law, which has the benefit of ease of implementation. Main theoretical resul...
