In particular, we focus on a general predator-prey-hunter system in which both the predator and prey may be harvested. Our goal is to design and test a controller that can maintain populations at prescribed target levels in the presence of uncertainty in the system dynamics and noisy measurements, while rejecting external disturbances. The dynamic equations of the model are based upon Brown et al. (2005, Marine Resource Economics), suitably modified for control systems design. Given this specification, we define a robust control problem and simulate its properties using the set of parameters for which performance of the closed-loop system is worst. One of the main advantages of using a robust control approach is that it provides deterministic tools for analysis of sensitivities and robustness to multiple uncertain parameters and affords the designer a framework to balance competing objectives. Simulations of the controlled system show promising results, with policy implications not only for managing existing predator-prey-hunter systems, but also for the planning of sustainable reintroduction efforts involving large, mammalian carnivores.","PeriodicalId":225201,"journal":{"name":"Proceedings of the 2011 American Control Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128714985","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 is the main reason why this interaction must be the major component of quasistatic and dynamic controls used in AFM instrumentation. Many dynamic control models are available for AFM but only few explicitly contain the tip-sample forces. One of them is based on asymptotic dynamics using Krylov-Bogoliubov-Mitropolsky (KBM) averaging. In the latter the tip-sample forces acting on approach and retraction are considered. Conservative Hertz model was applied in the first AFM simulations with KMB averaging. This simple and useful model does not cover many aspects of AFM tip-sample interactions (adhesion, energy dissipation, etc.) vital for accurate control of the instrument. The purpose of this paper is to provide adequate interaction force models for AFM control system and illustrate specific features, such as jumping between amplitude branches, adhesive avalanche, etc. These features are routinely observed in AFM experiments but mostly discarded in the control system. We suggest a hybrid model for the control system design to account for these phenomena. The model is based on matching the Maugis's JKR-DMT transition that describes elasto-adhesive interaction after geometrical contact (penetration) and the Integrated Lennard-Jones model with adhesive avalanche that describes the molecular level interaction before the contact. Matching parameters can be calculated based on the assumption that both curves describe the same physical interactions and must match smoothly at the common point of geometrical contact. Hybrid model algorithms are developed that can be used in AFM real-time adaptive control systems with parameter estimation.","PeriodicalId":225201,"journal":{"name":"Proceedings of the 2011 American Control Conference","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124548963","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}
