This study introduces a novel dual-mode distributed model predictive control (DMPC) approach for a class of dynamically coupled nonlinear systems, aiming to effectively mitigate input fluctuations. The existence of a terminal invariant region (TIR) and its corresponding terminal stabilizing controller (TSC) is rigorously established for a globally coupled nonlinear system subject to input amplitude and fluctuation constraints. When the system state resides within the global TIR, the global TSC ensures consistent satisfaction of input amplitude and fluctuation constraints. When operating outside the global TIR, a set of parallel model predictive controllers with input amplitude and fluctuation constraints is developed, where an aperiodic event-triggering scheduler is introduced to reduce the likelihood of input fluctuation constraint violations during practical numerical implementation. The recursive feasibility and closed-loop stability of the proposed dual-mode DMPC approach are rigorously analyzed. Simulation results on coupled oscillators demonstrate its effectiveness in input fluctuation mitigation and system stabilization.</div></div>","PeriodicalId":49450,"journal":{"name":"Systems & Control Letters","volume":"204 ","pages":"Article 106174"},"PeriodicalIF":2.1,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144519190","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}

We design the boundary feedback controller by backstepping method, where the control design is accelerated by neural operators. For backstepping kernel functions involving spatial variables, it is difficult to obtain the analytical solutions and time-consuming to compute the numerical solutions. In order to solve this problem, we use neural operator learning framework to accelerate the generation of approximate kernel functions, and then obtain the feedback controller. Specifically, we give the continuity and boundedness of the kernel partial differential equations (PDEs) and establish the nonlinear mapping of the reaction coefficient to the kernel functions. Through DeepONet approximation of nonlinear operator, we prove the existence of kernel PDEs under DeepONet arbitrary accuracy approximation. Then we design the DeepONet-approximated observer and output feedback controller, and demonstrate the output feedback stability of the closed-loop system under DeepONet approximations.

Whether disturbances destroy controllability of control systems is an important issue. For linear systems, it can be proved that disturbances do not influence controllability. However, for nonlinear systems, it is shown in this paper that disturbances may not destroy controllability but may even enhance it. More specifically, discrete-time commutative bilinear systems are first considered, and it is proved that such uncontrollable systems can be controllable when disturbances appear in the dynamics. Algebraic as well as geometric criteria for controllability of the discrete-time commutative bilinear systems with disturbances are derived, which are both necessary and sufficient conditions. Moreover, an algorithm for computing the required control inputs to achieve state transitions is also proposed. Finally, controllability of general discrete-time bilinear systems with disturbances is studied, which further demonstrates our observation on disturbances enhancing controllability.
