The characteristic of a shaking system is considered to be nonlinear and variable because of the influence of the test piece. In order to compensate for this problem, the influence of the disturbance force needs to be suppressed. The controller is designed using μ-synthesis by considering the uncertainty of the shaker. In order to investigate the control performance for the influence of friction and sloshing, the time waveform replication testing is executed. Finally, because the disturbance-force compensator suppresses the nonlinear characteristic, the good performance is confirmed with the help of experiments conducted using the actual equipment.","PeriodicalId":294950,"journal":{"name":"2009 IEEE Control Applications, (CCA) & Intelligent Control, (ISIC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124315318","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}

Indeed, controlling the speed and the energy in a complex SoCs - which adopt the Globally Asynchronous Locally Synchronous (GALS) paradigm - require specific power supplies and clock generators as actuators and dedicated sensors. The problem faced by the designers is the non-uniform and non-predictable behaviour of such systems which embed several microprocessors and complex Network-on-Chips (NoC). In these conditions, the control laws are difficult to establish. Moreover, with the technology shrink, the control needs are increased. In order to reach an acceptable fabrication yield, the clock synchronisation - based on the assumption that the critical path is shorter than the clock period - is impracticable with large SoCs which are divided in multiple clock domains. This is why specific sensors are used to evaluate the fabrication process quality and the local environmental parameters (voltage, temperature) in each clock region in order to determine the appropriate clock frequency which does not violate the local timing constraint. All these systems are fed back and required well-suited control techniques able to manage process variability as well as energy or speed.","PeriodicalId":294950,"journal":{"name":"2009 IEEE Control Applications, (CCA) & Intelligent Control, (ISIC)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114920953","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}

The presented design methodology guarantees desired output transient performance indices by inducing of two-time-scale motions in the closed-loop system where the controller dynamics is a singular perturbation with respect to the system dynamics. Stability conditions imposed on the fast and slow modes and sufficiently large mode separation rate between fast and slow modes can ensure that the full-order closed-loop nonlinear system achieves the desired properties in such a way that the output transient performances are desired and insensitive to external disturbances and plant's parameter variations. The novelty in the paper is that the high-frequency-gain online identification and adaptive gain tuning are incorporated in the control system in order to maintain the two-time-scale structure in the closed-loop system trajectories and stability of fast-motion transients for a large range of plant's parameter variations. The singular perturbation method is used through-out the paper in order to get explicit expressions for evaluation of the controller parameters. Numerical example and simulation results are presented.","PeriodicalId":294950,"journal":{"name":"2009 IEEE Control Applications, (CCA) & Intelligent Control, (ISIC)","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116800749","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}
