The plant dynamics of interest are known, discrete-time, single-input single-output (SISO), linear time-invariant (LTI), and nonminimum phase (NMP), with a single left-half-plane zero outside the unit circle. The approximate inversion methods are evaluated over a range of NMP zero locations and aggressive seek durations. Using a plant inverse (PI) architecture, we find that the ZPETC algorithm provides better settle performance for particular plants with a NMP zero near the unit circle. Conversely, the noncausal series approximation method achieves faster settle times when these plants' NMP zero is far from the unit circle. With a closed-loop inverse (CLI) architecture, both the series approximation and ZPETC algorithms yield faster settle times than either algorithm in PI, regardless of NMP zero location","PeriodicalId":265903,"journal":{"name":"2006 American Control Conference","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121734331","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 final objective of the manuscript is to design a robust control law capable of improving the tracking of each robot to its corresponding reference model in comparison to existing controllers when the slave is interacting with an obstacle while guaranteeing closed-loop stability. In this way, a multiestimation-based adaptive controller is proposed. Thus, the control scheme for each robot is composed of a set of estimation algorithms running in parallel along with a supervisory index proposed with the aim of evaluating the identification performance of each one. Hence, the master robot is able to follow more accurately the constrained motion defined by the slave when interacting with an obstacle than when a single estimation based controller is used. Finally, some simulation examples showing the working of the multiestimation scheme complete the paper","PeriodicalId":265903,"journal":{"name":"2006 American Control Conference","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115911108","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}

Such a strategy consists of a discretization of the plant by means of a fractional-order hold (FROH) with a multirate input in order to place the zeros of the discretized plant into the stability region. In this way, an adaptive controller can be designed so that the discretized plant asymptotically matches a stable reference model without any linking between the reference model zeros and those of the discretized plant. Such a controller ensures the matching of the reference model at sampling instants and the boundedness of the plant output for all time. An example is presented to illustrate this control strategy","PeriodicalId":265903,"journal":{"name":"2006 American Control Conference","volume":"24 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131456660","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}

To guarantee a good control performance, such a high sampling frequency might be required at some periods of time, but not necessarily continuously. By using an event-driven control scheme that triggers the update of the control value only when the (tracking or stabilization) error is large, the average processor load can be reduced considerably. Although event-driven control can be effective from a CPU-load perspective, the analysis of such control schemes is much more involved than that of conventional schemes and is a widely open research area. This paper investigates the control performance of an event-driven controlled continuous-time linear system with additive disturbances in terms of practical stability (ultimate boundedness). By using the derived results, the event-driven controller can be tuned to get satisfactorily transient behavior and desirable ultimate bounds, while reducing the required average processor load for its implementation. Several examples illustrate the theory","PeriodicalId":265903,"journal":{"name":"2006 American Control Conference","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129988067","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}

First, we provide a utility based approach to find the future price of weather derivatives, where the contract is assumed to be carried out between an insurance company and an industry that run a project affected by weather index, say, the average temperature. This situation is typical in the Japanese weather derivatives market, because most contracts are sold by insurance/finance companies and their price should be determined by taking asymmetric positions into account. Using an exponential utility function, it is shown that dealings may be executed at an equilibrium price with a suitable volume adjustment.
