Simultaneous imaging and nanomechanical mapping is needed to correlate the morphological and mechanical evolutions of the sample during the dynamic phenomena such as cell defusion process. However, current method to mechanical property mapping—the force-volume mapping technique—is limited to static elasticity mapping only, whereas the mechanical properties of soft materials are viscoelastic of frequency-dependence in nature. The proposed approach aims to address these challenges to enable simultaneous imaging and broadband nanomechanical mapping of soft materials in air. Specifically, it is proposed to augment a complex excitation input to the sample topography tracking during the imaging process. The proposed approach is illustrated through experimental implementation on a PDMS sample. The experimental results obtained demonstrate that by using the proposed technique, both topography imaging and broadband viscoelasticity quantification can be reliably achieved.","PeriodicalId":422926,"journal":{"name":"2017 American Control Conference (ACC)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126970021","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}

This architecture is structured in such a way that it admits quantifiable analysis of the closed-loop performance of the network of converters; the analysis simplifies to studying closed-loop performance of an equivalent single-converter system. The proposed architecture allows for the proportion in which the sources provide power to vary with time; thus overcoming limitations of our previous designs in [1]. Additionally, the proposed control framework is suitable to both centralized and decentralized implementations, i.e., the same control architecture can be employed for voltage regulation irrespective of the availability of common load-current (or power) measurement, without the need to modify controller parameters. The performance becomes quantifiably better with better communication of the demanded load to all the controllers at all the converters (in the centralized case); however guarantees viability when such communication is absent. Case studies comprising of battery, PV and generic sources are presented and demonstrate the enhanced performance of prescribed optimal controllers for voltage regulation and power sharing.","PeriodicalId":422926,"journal":{"name":"2017 American Control Conference (ACC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127870322","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 consists of heating the workpieces to a high temperature in order to transform the metal to austenite, followed by quenching in oil, water or brine. In this work, we report on potential improvements for the energy efficiency of a steel quench hardening process, currently in operation at an industrial partner, which can be achieved via model-based optimal control. To obtain a defect-free and structurally sound product, both the macroscopic temperature and microstructural properties of the workpieces need to be controlled. The novelty of this work lies in the modeling approach considered to solve the furnace energy consumption minimization problem. A previously-developed radiation-based model is used to evaluate the energy consumption and part temperature distribution as a function of the time of processing. Simultaneously, we predict the effects of process variables on microstructural evolution of the parts and their consequences on the hardness and toughness of the quenched product. A response surface method is used to find the optimal set points of the feedback controllers that minimize the furnace energy consumption without violating the heating requirements and the desired grain size. Furnace operation under optimal set points results in a significant energy efficiency gain of 3.5% when compared with the heuristic operation currently in place.","PeriodicalId":422926,"journal":{"name":"2017 American Control Conference (ACC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123928733","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}
