  摘要：This note studies stability of event-triggered control systems with the event-triggered control algorithm proposed in (Zhang et al., 2022). We construct a novel Halanay-type inequality, which is used to show that sufficient conditions of the main results in (Zhang et al., 2022) ensure stability of the event-triggered control systems that was missing in (Zhang et al., 2022). It is also shown that a positive parameter in the proposed event-triggering condition in (Zhang et al., 2022) can be free...

  摘要：This article deals with the embedding framework of Markov decision processes (MDPs) with discrete state and action space to find optimal actions. The optimal control problem of MDPs can be efficiently tackled by restructuring the same into an equivalent linearly-solvable Markov decision processes (LMDPs) through the method called embedding. However, state costs under the embedding may not exactly match the original costs and even assume unrealistic values. In this work, we derive a constructiv...
• Nongradient-Based Tracking of Environmental Field Isolines in a Changing Medium by Dubins-Vehicle Type Robots AI翻译

  摘要：A nonholonomic robot of a Dubins-vehicle type moves in a changing resistant medium, like water or air. The objective is to exhibit the extension of a spatial phenomenon (e.g., a critically contaminated area) related to a dynamic environmental field (e.g., a distribution of the contaminant concentration). Specifically, the robot should arrive at a certain level set of the field and repeatedly sweep it afterward. The field data come exclusively from online and pointwise measurements of the field...
• Data-Driven Safe Control of Uncertain Linear Systems Under Aleatory Uncertainty AI翻译
  作者：Modares, Hamidreza
  作者单位：Michigan State University
  摘要：Safe control of constrained uncertain linear systems under aleatory uncertainty is considered. Aleatory uncertainty characterizes random noises and is modeled by a probability distribution function (pdf). Data-based probabilistic safe controllers are designed for the cases where the noise pdf is 1) zero-mean Gaussian with a known covariance, 2) zero-mean Gaussian with an uncertain covariance, and 3) zero-mean non-Gaussian with an unknown distribution. Easy-to-check-model-based conditions for g...
• Asynchronous Quantized Control of Piecewise-Affine Systems AI翻译
  作者：Ning, Zepeng; Feng, Gang; Yin, Xunyuan
  作者单位：Nanyang Technological University; City University of Hong Kong
  摘要：This technical note proposes a novel asynchronous control approach for discrete-time piecewise-affine (PWA) systems with logarithmic quantization of both multiple inputs and multiple state measurements. Since the actual system state and the quantized state may not always be in the same operating region due to quantization-induced uncertainties, the operating modes of the PWA system and the controller that depends on the quantized states may be asynchronous. Aiming at reducing the computational...
• Distributed Model Predictive Control via Separable Optimization in Multiagent Networks AI翻译
  作者：Shorinwa, Ola; Schwager, Mac
  作者单位：Stanford University; Stanford University
  摘要：We present a distributed model predictive control method, which enables a group of agents to compute their control inputs locally while communicating with their neighbors over a communication network. While many distributed model predictive control methods require a central station for some coordination or computation of the optimization variables, our method does not require a central station, making our approach applicable to a variety of communication network topologies. With our method, ea...
• Robust Optimal Control of Biobjective Linear-Quadratic System With Noisy Observation AI翻译
  作者：Wang, Guangchen; Xing, Zhuangzhuang
  作者单位：Shandong University
  摘要：note is dedicated to a kind of partially observable linear-quadratic control problem with model uncertainty, where the coefficients of cost functional are uncertain representing different market conditions. By virtue of backward separation technique, stochastic maximum principle, as well as filtering method, a feedback form of candidate optimal control is designed. Moreover, through some delicate analysis, the existence of maximal reference probability lambda (& lowast;) is certified. A consid...
• Robust State-Estimator-Based Control of Uncertain Semi-Markovian Jump Systems Subject to Actuator Failures and Time-Varying Delay AI翻译
  作者：Yu, Jinpeng; Liu, Zhen; Shi, Peng
  作者单位：Qingdao University; Qingdao University; University of Adelaide
  摘要：This note presents a reformed state-estimator-based adaptive control strategy for uncertain delayed semi-Markovian jump systems (DSMJS) via sliding-mode technique. In comparison to most literature results requiring exact prior knowledge of system time delay, a linear state estimator not linking any control inputs is developed to cope with the case with unknown state delays. By virtue of the acquired state estimation, the establishment of both a new switching surface of linear-type (SSL) and th...
• Uniform Exponential Stability for a Schrodinger Equation and Its Semidiscrete Approximation AI翻译
  作者：Guo, Bao-Zhu; Zheng, Fu
  作者单位：North China Electric Power University; Chinese Academy of Sciences; Academy of Mathematics & System Sciences, CAS; Hainan University
  摘要：In this article, we investigate the uniform exponential stability of a semidiscrete scheme for a Schrodinger equation under boundary stabilizing feedback control in the natural state space L-2(0,1). This study is significant since a time domain energy multiplier that allows proving the exponential stability of this continuous Schrodinger system has not yet found, thus leading to a major mathematical challenge to the uniform exponential stability of the corresponding semidiscretization systems,...
• Simultaneous Position and Orientation Planning of Nonholonomic Multirobot Systems: A Dynamic Vector Field Approach AI翻译
  作者：He, Xiaodong; Li, Zhongkui
  作者单位：University of Science & Technology Beijing; Peking University
  摘要：This article considers the simultaneous position and orientation planning of nonholonomic multirobot systems. Different from common research works, which only focus on final position constraints, we model the nonholonomic mobile robot as a rigid body and introduce both of position and orientation constraints for the robot's final states. In other words, the robot should not only reach the specified position, but also point to the desired orientation simultaneously. The challenge of this proble...
