The full state information is sampled periodically, but transmitted over communication networks to the controller aperiodically according to an event-triggering strategy. The sequence of the event-triggering transmission instants is certainly a subset of that of the time-triggering sampling instants. Hence the time-triggering strategy prevents the event-triggering strategy from the so-called Zeno behavior immediately. We employ the emulation-based approach and divide the controller design procedure into two steps. First, we present a time-triggered controller guaranteeing the global exponential absolute stability for the resulting closed-loop Lur'e system. The obtained sufficient stability conditions involving the state feedback gain matrix and the constant sampling period are derived by means of absolute stability theory. Subsequently, its robustness is analyzed against the control input error induced by the event-triggering mechanism. Under a prescribed periodic event-triggering strategy with a freely selectable parameter, a periodic event-triggered controller is obtained for the Lur'e system to achieve practical exponential absolute stabilization. Finally, linear matrix inequality (LMI) techniques are used to compute all the control parameters.","PeriodicalId":179068,"journal":{"name":"2019 China-Qatar International Workshop on Artificial Intelligence and Applications to Intelligent Manufacturing (AIAIM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116626167","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}

Since each agent has nonlinear dynamics, the system is no longer asymptotically null controllable with bounded controls (ANCBC). As a result, the widely-accepted low-gain feedback method for designing consensus protocols of MASs with input saturation can no longer work. According to the stability theory of impulsive systems and with the properties of convex hull, corresponding distributed impulsive consensus protocols are proposed. Finally, the effectiveness of the proposed anti-saturation impulsive consensus algorithm is validated by extensive numerical experiments.","PeriodicalId":179068,"journal":{"name":"2019 China-Qatar International Workshop on Artificial Intelligence and Applications to Intelligent Manufacturing (AIAIM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129453155","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}
