However, as a feature of a dynamic system, global temporal observability is embedded into classical observability. The necessary condition for global temporal observability is presented. Four linear systems were considered to test the proposed concept. Since observability is a binary test, our results matched the results of classical observability analysis when appropriate basis functions are utilized. The advantages and disadvantages of the proposed concept are discussed. The main advantage of global temporal observability is that it restores the state function for the entire time duration in a single step that requires matrix inversion. It is shown that global temporal observability connects state reconstruction, differential equations, and observability concepts.</div></div>","PeriodicalId":29926,"journal":{"name":"IFAC Journal of Systems and Control","volume":"32 ","pages":"Article 100312"},"PeriodicalIF":1.8,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143928557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It also enhanced subsonic flow stability by 10%–15% under choked flow conditions.

On the one hand, a multivariable feedback control design approach, using the concepts of control allocation and measurement combination. On the other hand, the mapping of a set of linear stabilizing controllers onto a multi-controller, based on the Q-parameter from the Youla-Kucera theory. In this context, the set of controllers can be designed independently. Moreover, the stability is guaranteed subject to an arbitrary switching between different stabilizing controllers. The procedure is evaluated by considering two relevant scenarios of control reconfiguration: 1- a complete modification of the input–output pairing, and 2- the replacement of a classical controller with a new advanced control strategy. Based on the computational simulation of two case studies from the literature, it is shown that the plug-in module carries out the reconfiguration of the control structure, improving the dynamic performance and ensuring the stability of the system.

Nonetheless, the success of these policies is also closely intertwined with the necessity of preserving a delicate social balance when allocating resources toward a widespread transition. In response to this issue, we propose to adopt the recently proposed Fair-MPC scheme to introduce a control-oriented framework to aid policymakers in designing sustainability policies that are both effective and fair and evaluating existing policies by looking at these two key facets of sustainable technology diffusion. The modular design of our tool enables the assessment of fairness objectives integrated within the policy design strategy, striking a balance between impartial <em>equality</em> and inclusive <em>equity</em> with the imperative of cost minimization and effective diffusion of the transition process. Meanwhile, the flexibility of the framework makes it applicable to various scenarios, potentially representing a key tool in supporting all sectors involved in the energy transition. In this work, we prove its usability through its data-driven application in the context of the green mobility transition. Our analyses reveal that pursuing fairness objectives leads to a decrease (even if minor) in diffusion performance, underscoring the delicate balance between these frequently conflicting goals and highlighting the necessity of having quantitative tools to navigate the complexities characterizing social contexts.</div></div>","PeriodicalId":29926,"journal":{"name":"IFAC Journal of Systems and Control","volume":"32 ","pages":"Article 100317"},"PeriodicalIF":1.8,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144230521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
