  摘要：this article, we derive direct data-driven dissipativity analysis methods for linear parameter-varying (LPV) systems using a single sequence of input- scheduling-output data. By means of constructing a semidefinite program subject to linear matrix inequality constraints based on this data-dictionary, direct data- driven verification of ( Q, S, R )-type of dissipativity properties of the data-generating LPV system is achieved. Multiple implementation methods are proposed to achieve efficient co...

  摘要：We address the problem of output redundancy in discrete-time linear systems, with the aim of obtaining an optimized combination of sensors for structurally rejecting certain disturbances.We frame our goal as the design problem of a nonlinear observer consisting in a linear Luenberger structure augmented with an adaptive weighted pseudoinverse combination of the available measurements. A novel optimization algorithm is proposed for the update of the dynamic weights of the pseudoinverse, togethe...
• Control Barrier Functions for Stochastic Systems and Safety-Critical Control Designs AI翻译

  摘要：In recent years, the analysis of a control barrier function has received considerable attention because it is helpful for the safety-critical control required in many control application problems. While the extension of the analysis to a stochastic system studied by many researchers, it remains a challenging issue. In this article, we consider sufficient conditions for reciprocal and zeroing control barrier functions ensuring safety with probability one and design a control law using the funct...

  摘要：A cascade connection comprising a delay, a partial differential equation (PDE), and an ordinary differential equation (ODE) is referred to as distributed if an integral operator of the functional state of the delay or the PDE enters, as a scalar, the next system in the cascade, or if the ODE state acts as an input to the PDE throughout the PDE's domain. While boundary control of systems involving PDEs or delays typically calls for the PDE backstepping approach, such distributed interconnection...

  摘要：We consider optimal control problems which consist in minimizing the L-infinity norm of an output function under an isoperimetric or L-1 inequality. These problems typically arise in control applications when one looks to minimizing the maximum trajectory deviation or peak under a budget constraint. We show a duality with more classical problems which amount to minimizing the L-1 cost under the state constraint given by an upper bound on the L-infinity norm of the output. More precisely, we pr...
• K-Monotonicity and Feedback Synthesis for Incrementally Stable Networks AI翻译

  摘要：We discuss the role of monotonicity in enabling numerically tractable modular control design for networked nonlinear systems. We first show that the variational systems of monotone systems can be embedded into positive systems. Utilizing this embedding, we show how to solve a network stabilization problem by enforcing monotonicity and exponential dissipativity of the network subcomponents. Such modular approach leads to a design algorithm based on a sequence of linear programming problems.
• Bounded Synthesis and Reinforcement Learning of Supervisors for Stochastic Discrete Event Systems With LTL Specifications AI翻译

  摘要：In this article, we consider supervisory control of stochastic discrete event systems (SDESs) under linear temporal logic specifications. Applying the bounded synthesis, we reduce the supervisory synthesis to the problem of satisfying a safety condition. First, we consider a directed controller that allows at most one controllable event to be enabled. We assign a negative reward to the unsafe states and introduce an expected return with a state-dependent discount factor. We compute a winning r...
• Gradient Play in Stochastic Games: Stationary Points, Convergence, and Sample Complexity AI翻译
  作者：Zhang, Runyu; Ren, Zhaolin; Li, Na
  作者单位：Harvard University
  摘要：In this article, we study the performance of the gradient play algorithm for stochastic games (SGs), where each agent tries to maximize its own total discounted reward by making decisions independently based on current state information, which is shared between agents. Policies are directly parameterized by the probability of choosing a certain action at a given state. We show that Nash equilibria (NEs) and first-order stationary policies are equivalent in this setting, and give a local conver...
• Secure Distributed Dynamic State Estimation Against Sparse Integrity Attack via Distributed Convex Optimization AI翻译
  作者：Li, Zishuo; Mo, Yilin
  作者单位：Tsinghua University; Tsinghua University
  摘要：In this article, we study the problem of distributed estimation of discrete-time LTI systems with bounded noise against sparse integrity attacks. A malicious adversary can corrupt an unknown set with $p$ out of $m$ sensors and manipulate their observations arbitrarily. We propose a general secure estimation framework by decomposing a centralized linear observer into local ones and fusing the local estimates by minimizing specially designed convex functions. The optimization problem can be solv...

  摘要：The coupled Riccati equations (CREs) are a set of multiple Riccati-like equations whose solutions are coupled with each other through matrix means. They are a fundamental mathematical tool to depict the inherent dynamics of many complex systems, including Markovian systems or multiagent systems. This article investigates a new kind of CREs called harmonic-CREs (HCREs), whose solutions are coupled using harmonic means. We first introduce the specific form of HCREs and then analyze the existence...
