• Warm Start of Mixed-Integer Programs for Model Predictive Control of Hybrid Systems AI翻译

  摘要：In hybrid model predictive control (MPC), a mixed-integer quadratic program (MIQP) is solved at each sampling time to compute the optimal control action. Although these optimizations are generally very demanding, in MPC, we expect consecutive problem instances to be nearly identical. This article addresses the question of how computations performed at one time step can be reused to accelerate (warm start) the solution of subsequent MIQPs. Reoptimization is not a rare practice in integer progra...

  摘要：In this article, we present a fault diagnosis approach for discrete event systems using labeled Petri nets. In contrast to the existing works, a new fault class containing all the fault transitions is additionally introduced in the diagnosis function, leading to a more informative and precise diagnosis result. An integer linear programming (ILP) problem is built according to an observed word. By specifying different objective functions to the ILP problem, the diagnosis result is obtained witho...

  摘要：We consider policy evaluation in infinite-horizon discounted Markov decision problems with continuous compact state and action spaces. We reformulate this task as a compositional stochastic program with a function-valued decision variable that belongs to a reproducing kernel Hilbert space (RKHS). We approach this problem via a new functional generalization of stochastic quasi-gradient methods operating in tandem with stochastic sparse subspace projections. The result is an extension of gradien...
• Global Practical Tracking Via Adaptive Output Feedback for Uncertain Nonlinear Systems Without Polynomial Constraint AI翻译
  作者：Wang, Yuan; Liu, Yungang
  作者单位：Shandong University
  摘要：This article investigates global practical output tracking via adaptive output feedback for a class of uncertain nonlinear systems. Remarkably, the control problem under investigation is in the context of unknown control directions and output feedback, which severely restricts the system nonlinearities. Nevertheless, the growth on the unknown system nonlinearities in this article is extended from polynomial (of output) to arbitrary function, and meanwhile no further a priori information is req...
• On Topological Properties of the Set of Stabilizing Feedback Gains AI翻译

  摘要：This article presents a fairly complete account on various topological and metrical aspects of feedback stabilization for single-input single-output (SISO) continuous and discrete time linear time-invariant (LTI) systems. In particular, we prove that the set of stabilizing output feedback gains for a SISO system with n states have at most inverted right perpendicularn 2inverted left perpendicular connected components. Furthermore, our analysis yields an algorithm for determining intervals of s...
• Asynchronous Gradient Push AI翻译

  摘要：We consider a multiagent framework for distributed optimization where each agent has access to a local smooth strongly convex function, and the collective goal is to achieve consensus on the parameters that minimize the sum of the agents' local functions. We propose an algorithm wherein each agent operates asynchronously and independently of the other agents. When the local functions are strongly convex with Lipschitz-continuous gradients, we show that the iterates at each agent converge to a ...
• Practical Synchronization in Networks of Nonlinear Heterogeneous Agents With Application to Power Systems AI翻译
  作者：Chowdhury, Dhrubajit; Khalil, Hassan K.
  作者单位：Michigan State University
  摘要：In this article, we consider the synchronization problem in a network of nonlinear multiagent systems having the same relative degree r. The agents do not have access to their state or output and only have relative output information from their neighbors. The controller structure is decentralized in nature and, therefore, depends only on the relative information available to it. The agent dynamics are transformed into relative dynamics by a change of coordinates where the agent dynamics are co...
• Model-Based Dynamic Event-Triggered Control for Systems With Uncertainty: A Hybrid System Approach AI翻译
  作者：Liu, Kun-Zhi; Teel, Andrew R.; Sun, Xi-Ming; Wang, Xue-Fang
  作者单位：Dalian University of Technology; University of California System; University of California Santa Barbara
  摘要：In this article, the event-triggered control problem for linear systems with uncertainties is addressed. A model-based dynamic event-triggered transmission strategy is proposed for linear systems, and for systems that can be decomposed into interconnected subsystems, a distributed model-based dynamic event-triggered transmission strategy is also proposed with transmission delays and transmission protocols in the networks. The whole systems are modeled into a hybrid system framework by introduc...
• Small-Time Local Controllability of Switched Nonlinear Systems AI翻译
  作者：Meng, Qingkai; Yang, Hao; Jiang, Bin

  摘要：This article considers the small-time local controllability (STLC) of switched nonlinear systems (SNSs). First, the original SNS is associated with a nilpotent Lie algebra, on which the solutions of the SNS are approximated by the hybrid Lie power series. Second, the concepts of high-order control variations and bad Lie brackets are defined for SNSs from a geometrical point of view. This helps to establish a new high-order sufficient STLC condition that is closely related to neutralized bad Li...

  摘要：An output robust adaptive control is designed for a class of Lipschitz nonlinear systems under assumption that the measurements are available with a constant bias and the state equations linearly parameterized by unknown parameters and external disturbances. A dynamic state reconstruction (synthesis of an observer) is avoided by using delayed values of the output in the feedback and adaptation laws. The analysis of robust stability for the resulted time-delay system is performed by using the L...
