Firstly, we introduce variable substitutions to simplify the mathematical model of marine surface vessels. Then, a prescribed-time extended state observer is constructed to estimate unmeasured velocities and compound uncertainties at a prescribed-time. Meanwhile, a novel prescribed-time performance function with an error transformation is designed to impose constraints on formation errors. Subsequently, we design an event-triggered control mechanism taking account of error constraints, which reduces the operating frequency of actuators without weakening system transient performance. Based on the designed extended state observer, performance function and event-triggered control mechanism, a prescribed-time distributed formation control law is developed for marine surface vessels with distinguished convergence performance, good transient performance, and low actuator losses. At last, simulations are conducted to illustrate the advantages and application prospects of the designed approach. The proposed method has several notable characteristics compared with most existing strategies: 1) it guarantees the prescribed-time convergence of the formation errors; 2) it achieves prescribed-time error constraints by using the designed performance function; 3) it actualizes the quantitative balance between error constraints and the operating frequency of actuators via the proposed event-triggered control mechanism, which can avoid the excessive wear on actuators.</div></div>","PeriodicalId":50980,"journal":{"name":"Applied Mathematical Modelling","volume":"145 ","pages":"Article 116117"},"PeriodicalIF":4.4,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143748333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The trampoline metamaterial incorporates periodically arranged composite resonant pillars embedded in a perforated thin plate. By designing a point defect in the metamaterial, vibro-acoustic energy can be intentionally confined to the defect location at the defect band frequency. Considering the amplified acoustic pressure in the Helmholtz resonator, the incorporation of the trampoline metamaterial into a Helmholtz resonant cavity enables enhanced energy localization. Initially, a mathematical model for calculating the first resonant band gap is established. The band gap and corresponding defect band frequency are then validated by comparing numerical simulation with experimental results. Subsequently, numerical simulations are conducted to investigate the influences of hole radius and coupled structure on piezoelectric energy harvesting performance. These simulations revealed that an increase in the hole radius significantly enhances vibro-acoustic localization and piezoelectric conversion efficiency of the trampoline metamaterial. Furthermore, the synergistic interaction of the coupled structure between the defect state in the trampoline metamaterial and the acoustic pressure amplification in the Helmholtz resonator further enhances the energy harvesting performance. At an acoustic incident amplitude of 2 Pa and a defect band frequency of 1068.5 Hz, the coupled structure attains a maximum output voltage of 5.94 V and power of 39.10 μW.

Both single- and two-phase flow modeling are considered in the present paper. First, the derivation of the models through the integration of the 3-D equations over the radially deformable inner pipe cross-section is described. Then, the Coleman-Noll procedure is used in order to formulate constitutive/closure laws consistent with the second law of thermodynamics leading to entropy consistent models. For elastically deformable pipes, an additional closure law relating the elastic variation of the cross-section area with the internal fluid pressure is also considered. The derivation of this closure law, classically referred to as the tube law, is also discussed here. This effective averaging procedure leads to non-conservative terms in the one-dimensional models linked to the pressure effects due to the spatial and temporal cross-section variations. The mathematical properties of the obtained system of partial differential equations, i.e. hyperbolicity, the structure of the waves, the expression of the Riemann invariants and the existence of a mathematical entropy, are then examined. In addition, the consequences of the definition of shock-waves for these models are also discussed. The Euler equations are first considered and analyzed in this context. Then, the approach is extended to more advanced compressible two-phase flow modeling. The two examples considered in the present paper are the Kapila five-equation and the Baer-Nunziato seven-equation models involving non-conservative terms due to the change of volume fraction in the balance equations which are for the first time investigated in this context.
