This research investigates the stochasticity of the adaptive cruise control empirically, and proposes a robust RSS regarding longitudinal driving. We firstly show that there exists certain time-variant stochasticity in the ACC controlled vehicle using real world dataset, and numerically calculated the probability that the RSS may be violated when the noise is considered, which reveals that RSS violation is inevitable under certain scenarios. Then, an explicit solution of the noise disturbed ACC is derived.

The sensors receive a reflected signal from the target where the time-of-arrival (TOA) renders the distance information. The existing approaches include: (i) classic centralized solutions which gather and process the target data at a central unit, (ii) distributed solutions which assume that the target data is observable in the dense neighborhood of each sensor (to be filtered locally), and (iii) double time-scale distributed methods with high rates of communication/consensus over the network. This work, in order to reduce the network connectivity in (i)-(ii) and communication rate in (iii), proposes a distributed single time-scale technique, which can also handle heterogeneous constant data-exchange delays over the static sensor network. This work assumes only <em>distributed observability</em> (in contrast to local observability in some existing works categorized in (ii)), i.e., the target is observable globally over a (strongly) connected network. The (strong) connectivity further allows for <em>survivable network</em> and <span><math><mi>q</mi></math></span><em>-redundant observer design</em>. Each sensor locally shares information and processes the received data in its immediate neighborhood via local linear-matrix-inequalities (LMI) feedback gains to ensure tracking error stability. The same gain matrix works in the presence of heterogeneous delays with no need of redesigning algorithms. Since most existing distributed estimation scenarios are linear (based on consensus), many works use <em>linearization</em> of the existing <em>nonlinear TDOA measurement models</em> where the output matrix is a function of the target position. As the exact target position is unknown, the existing works use <em>estimated</em> position in the output matrix (and for the gain design) at every time step. This makes their algorithm more complex and less accurate. Instead, this work provides a <em>modified</em> linear TDOA measurement model with a <em>constant</em> output matrix that is independent of target position and more practical in distributed linear setups.</div></div>","PeriodicalId":49450,"journal":{"name":"Systems & Control Letters","volume":"196 ","pages":"Article 106009"},"PeriodicalIF":2.1,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143182991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our method is based on scenario optimization combined with recent formulations for direct data-driven control. We derive upper bounds on the minimal amount of data required to provably achieve quadratic stability for probabilistic systems with aleatoric uncertainty and demonstrate the benefits of our data-driven method through a numerical example.
