The HNSCA combines the Nonlinear Sine Cosine Algorithm (NSCA) with Adaptive Safe Experimentation Dynamics (ASED) to fine-tune FT-PPC-PID parameters, achieving rapid transient response and system stability. Simulation results demonstrate significant improvements over other optimization variants like ESCA and ASCA, including a 96% faster rise time, 61.9% reduction in settling time, and 6.4% lower overshoot. Additionally, HNSCA reduced pressure oscillations by 25%–30%, lowered power consumption by 20%–30%, and achieved up to a 50% reduction in energy consumption under a 10 kg load. It also enhanced subsonic flow stability by 10%–15% under choked flow conditions.

This is specifically challenging when the learning process starts with no data and rich data must be collected from the closed-loop system. This is in sharp contrast to the standard practice in data-driven control that assumes the availability of a priori rich collected open-loop data. To ensure that the closed-loop system delivers acceptable performance despite exploration for rich data collection in the context of linear quadratic regulator (LQR), we first formalize a linear matrix inequality (LMI) solution for an LQR problem that is regularized by the control entropy. Given available side information (e.g., a set that system parameters belong to), a conservative solution to the LQR can be found. To reduce the conservatism over time while ensuring an acceptable performance during learning, we present a set membership closed-loop system identification and integrate it with side information in solving the entropy-regularized LQR through Schur complement, along with the lossy S-procedure. We show that the presented set membership approach progressively improves the entropy-regularized LQR cost by shrinking the size of the set of system parameters. We also show that this is achieved while guaranteeing acceptable performance. An iterative algorithm is presented using the closed-loop set membership learning to progressively learn a new improved controller after every online data sample is collected by applying the current learned control policy. Simulation examples are provided to verify the effectiveness of the presented results.</div></div>","PeriodicalId":29926,"journal":{"name":"IFAC Journal of Systems and Control","volume":"32 ","pages":"Article 100305"},"PeriodicalIF":1.8,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143739293","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}

The proposal is based on a multi-controller switching philosophy, where the modification of an interpolation signal defines the combination of the control actions of each controller. The contribution is based on the integration of two methodologies. 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. The design is based on the nominal controller, which is not modified during the reconfiguration process. In addition, it can be easily implemented online, connected to input–output terminals of the existing controller.</div></div>","PeriodicalId":29926,"journal":{"name":"IFAC Journal of Systems and Control","volume":"32 ","pages":"Article 100302"},"PeriodicalIF":1.8,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143698000","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}
