  摘要：In this article, asymptotical stabilization of probabilistic Boolean control networks with a switching signal being an independent identically distributed process has been systematically studied. Here, the binary operators connecting logical functions of state nodes and pinning controllers are constrained to certain sets. By establishing matrix representation of operators and input constraints, several criteria for asymptotical stabilization have been established. The proposed asymptotical sta...
• On 1-D PDE-Based Cardiovascular Flow Bottleneck Modeling and Analysis: A Vehicular Traffic Flow-Inspired Approach AI翻译

  摘要：We illustrate the potential of partial differential equation (PDE)-based traffic flow control in cardiovascular flow analysis, monitoring, and control, presenting a PDE-based control-oriented formulation, for one-dimensional (1-D) blood flow dynamics in the presence of stenosis. This is achieved adopting an approach for modeling and analysis that relies on the potential correspondence of 1-D blood flow dynamics in the presence of stenosis, with 1-D traffic flow dynamics in the presence of bott...
• Receding Horizon Control With Online Barrier Function Design Under Signal Temporal Logic Specifications AI翻译

  摘要：Signal temporal logic (STL) has been found to be an expressive language for describing complex, time-constrained tasks in several robotic applications. Existing methods encode such specifications by either using integer constraints or by employing set invariance techniques. While in the first case this results in a mixed integer linear program (MILP), control problems, in the latter case, designer-specific choices may induce conservatism in the robot's performance and the satisfaction of the t...

  摘要：This article provides an approximate online adaptive solution to the infinite-horizon optimal tracking problem for control-affine continuous-time nonlinear systems with uncertain drift dynamics. A model-based approximate dynamic programming (ADP) approach, which is facilitated using a concurrent learning-based system identifier, approximates the optimal value function. To reduce the computational complexity of model-based ADP, the state space is segmented into user-defined segments (i.e., regi...
• Global Convergence of Policy Gradient Primal-Dual Methods for Risk-Constrained LQRs AI翻译

  摘要：While the techniques in optimal control theory are often model-based, the policy optimization (PO) approach directly optimizes the performance metric of interest. Even though it has been an essential approach for reinforcement learning problems, there is little theoretical understanding of its performance. In this article, we focus on the risk-constrained linear quadratic regulator problem via the PO approach, which requires addressing a challenging nonconvex constrained optimization problem. ...
• Approximate Dissipativity of Cost-Interconnected Systems in Distributed Economic MPC AI翻译

  摘要：We consider dissipativity properties of interconnected systems in the context of distributed economic model predictive control (MPC), with the subsystems being interconnected through their stage cost functions. The isolated subsystems, i.e., when neglecting the coupled portion of the individual stage costs, are assumed to be dissipative with respect to a specific supply rate related to their local stage cost function, which is commonly used in an economic MPC context. Based on these local diss...
• Leaderless Consensus of Heterogeneous Multiple Euler-Lagrange Systems With Unknown Disturbance AI翻译

  摘要：This article studies the leaderless consensus problem of heterogeneous multiple networked Euler-Lagrange systems subject to persistent disturbances with unknown constant biases, amplitudes, initial phases, and frequencies. The main characteristic of this study is that none of the agents has information of a common reference model or of a common reference trajectory. Therefore, the agents must simultaneously and in a distributed way: achieve consensus to a common reference model (group model); ...

  摘要：The average impulsive interval is widely used to describe the frequency of impulsive occurrence (FIO), where the occurrence number of impulses is bounded by a linear function of time interval length. However, the linear relationship may insufficiently or excessively characterize the occurrence number of impulses to stabilize impulsive time-varying systems. In this article, the impulsive density is introduced to describe a time-varying FIO, such that the occurrence number of impulses can be cha...
• Robust Model Predictive Control Using a Two-Step Triggering Scheme AI翻译
  作者：Deng, Li; Shu, Zhan; Chen, Tongwen
  作者单位：University of Alberta
  摘要：This article is concerned with event-triggered robust model predictive control for linear discrete-time systems with bounded disturbances. A two-step scheme involving a tentative verification of a triggering condition and a delayed triggering with a waiting horizon is proposed to reduce the average triggering rate and fully utilize the nominal optimal control sequence minimizing a quadratic cost function. The triggering condition and the waiting horizon are synthesized based on a prediction mo...

  摘要：Input delay could lead to instability of an impulsive control system. However, the problem of input delay has been seldom studied. This work addresses the fundamentally important problem in impulsive control theory. By a novel approach, we establish Lyapunov-Razumikhin-type theorems on exponential stability of stochastic impulsive delay systems. Based on our fundamental results, we develop a foundational theory for the impulsive stabilization of stochastic delay systems with input delay. Our p...
