We contend that existing stability results may be overly conservative when sojourn times are treated as stochastic rather than arbitrary over intervals. This motivates our investigation into stochastic stability criteria for impulsive switched systems, where the sojourn times of impulsive switching signals obey uniform distributions over intervals. Our first theoretical contribution offers an exact formula for the component-wise first moment of the state for linear impulsive switched systems, expressed in terms of a solution to an auxiliary linear time-delay system. We extend this approach to nonlinear systems by leveraging a multiple Lyapunov function assumption. Consequently, the exponential mean stability of such impulsive switched systems can be determined by assessing the stability of the auxiliary systems. Nevertheless, this method fails to establish exponential mean stability when the impulsive switched system has unstable subsystems. To address this limitation, we conduct an in-depth frequency domain analysis, revealing a common occurrence of pole-zero cancellation. Leveraging these insights, we propose a non-conservative approach for stability analysis. Simulations demonstrate that our proposed stability criteria effectively determine stability in scenarios where all subsystems are unstable, or instability when all subsystems are stable.</p></div>","PeriodicalId":49450,"journal":{"name":"Systems & Control Letters","volume":"193 ","pages":"Article 105917"},"PeriodicalIF":2.1,"publicationDate":"2024-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142149634","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}

By “prescribed-time stability”, we refer to the property of having the main state of the system converge to a particular compact set of interest before a given time defined <em>a priori</em> by the user. We focus on hybrid systems that achieve this property via time-varying gains. For continuous-time systems, this approach has received significant attention in recent years, with various applications in control, optimization, and estimation problems. However, its extensions beyond continuous-time systems have been limited. This gap motivates this paper, which introduces a novel class of switching conditions for switching systems with resets that incorporate time-varying gains, ensuring the PT-S property even in the presence of unstable modes. The analysis leverages tools from hybrid dynamical system’s theory, and a contraction–dilation property that is established for the hybrid time domains of the solutions of the system. We present the model and main results in a general framework, and subsequently apply them to two different problems: (a) PT control of dynamic plants with uncertainty and intermittent feedback; and (b) PT decision-making in non-cooperative switching games using algorithms that incorporate momentum, resets, and dynamic gains. Numerical results are presented to illustrate all our results.</p></div>","PeriodicalId":49450,"journal":{"name":"Systems & Control Letters","volume":"193 ","pages":"Article 105910"},"PeriodicalIF":2.1,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0167691124001981/pdfft?md5=7113c8ef717731574333b9b3f2ebc7b1&pid=1-s2.0-S0167691124001981-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142149632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we present a setting which generalizes a rigid-motion in Euclidean space to rigid-motion in space–time. A kinematic feedback law is presented and proved to almost globally stabilize a rigid-motion in space–time. This setting defines the kinematics on a class of Lie group whose inverse is a function of its transpose and associated metric tensor. It is shown that the Special Euclidean Group is a limiting case of this class of Lie group and this alternative viewpoint can be utilized in stability proofs for rigid-motion kinematic control.

To remove the need for the persistently exciting (PE) condition of a sufficiently high order on pre-collected data, a set containing all systems capable of generating such data is constructed. Then, at each time step, an upper bound on a given objective function is derived for all systems in the set, and a feedback controller is designed to minimize this bound. The optimal control gain at each time step is determined by solving a set of linear matrix inequalities. We prove that if the synthesis problem is feasible at the initial time step, it remains feasible for all future time steps. Unlike current data-driven predictive control schemes based on behavioral system theory, our approach requires less stringent conditions for the pre-collected data, facilitating easier implementation.
