摘要：We study the linear quadratic Gaussian (LQG) control problem, in which the controller's observation of the system state is insufficient to attain a desired quadratic control cost. To achieve the desired LQG cost, we introduce a communication link from the observer (encoder) to the controller (decoder). We investigate the fundamental tradeoff between a desired LQG cost and the required communication (information) resources, measured with the conditional directed information. The optimization do...

摘要：When the H-8 loop-shaping controller is implemented as a unity feedback system, its step responses are sometimes unsuitable for tracking control, typically, displaying large overshoots. In this article, the implementation method is studied for tracking control with small overshoots. Three implementation methods that are described by a unity feedback system, a previous simple two-degrees-of-freedom (2DoF) system, and a new simple 2DoF system proposed in this article are examined. For the closed...

摘要：In this article, we study the leader-following problem for linear stochastic multiagent systems with uniform and constant communication delays on directed or undirected graphs. We consider both the state feedback and output feedback solutions. In the latter case, the agents can be a set of heterogeneous linear systems. By resorting to a new approach based on the scalar Lambert equation, we obtain a constructive design with less conservative closed-form delay bounds. In particular, it is possib...

摘要：Classical sufficient conditions for ensuring the robust stability of a dynamical system in feedback with a nonlinearity include passivity, small gain, circle, and conicity theorems. In this article, we present a generalized version of these results for arbitrary semi-inner product spaces. Our result is purely algebraic, and holds even when the conventional discrete or continuous-time causal dynamical systems are replaced by general nonlinear relations, where there need not exist a notion of ti...

摘要：In this article, we model a hybrid system by using a hybrid machine consisting of an automaton and a set of continuous-variable subsystems. We investigate the problem of determining the (current) discrete state of the hybrid system. Extending the terminologies in discrete-event systems, a hybrid system is detectable if its discrete state can be uniquely determined. We derive conditions for a hybrid system to be detectable. If a hybrid system is detectable, we determine its current discrete sta...

摘要：As an important branch of evolutionary game theory, iterated games describe the situations that interacting agents play repeatedly based on previous outcomes by using the conditional strategies. A new class of zero-determinant (ZD) strategies, which can control a linear relation between the expected payoffs of a single agent and the coplayers, has dramatically changed the viewpoint on iterated games. Here, in this article, we focus on the decision-making behaviors in iterated multiplayer gamin...

摘要：The goal of this article is to investigate under what conditions a Boolean control network admits a state feedback control law that makes the resulting Boolean network reconstructible. Starting from an algebraic representation of the Boolean control network, we first propose a result that allows to significantly reduce the problem size, and hence to mitigate the curse of dimensionality that typically arises when dealing with logical systems of very large size. Subsequently, we provide a necess...

摘要：In this work, we study Stackelberg equilibria for discounted stochastic games. We consider two solution concepts for these games: stationary strong Stackelberg equilibrium (SSSE) and fixed point equilibrium (FPE) solutions. The SSSE solution is obtained by explicitly solving the Stackelberg equilibrium conditions, whereas the FPE can be computed efficiently using value or policy iteration algorithms. However, previous work has overlooked the relationship between these two different solution co...

摘要：This article presents a method that convexifies state-constrained optimal control problems in the control-input space. The proposed method enables convex programming methods to find the globally optimal solution even if costs and control constraints are nonconvex in control and convex in state, dynamics is nonaffine in control and convex in state, and state constraints are convex in state. Under the above conditions, generic methods do not guarantee to find optimal solutions, but the proposed ...

摘要：This article proposes a new model predictive control (MPC) control scheme for polytopic uncertain and/or time-varying systems with state and input constraints. The MPC policies we consider employ: 1) the intersection of ellipsoids to characterize the domain of attraction, 2) a time-varying Lyapunov function to bound from above the cost function, 3) a tailored alternating direction method of multipliers algorithm to solve efficiently the online optimization problem. With respect to other well-k...
