In plug-and-play control the communication of control algorithms and system models over a shared network is concerned with the intention to adjust control laws automatically after the occurrence of changes in the plant structure or in the control objectives. An application scenario is the break down of a sensor or an actuator as studied in fault-tolerant control. This paper investigates such a situation in the sense of plug-and-play control. The diagnostic task and reconfiguration task are separated and assigned to predestined computational units: an onboard unit allocated at the plant with access to the plant signal and a remote off-board unit concerning the expensive computation. The onboard diagnostic unit detects and identifies the failure at runtime and transmits the model of the faulty plant to the offboard reconfiguration unit over a shared network. Using the reconfiguration strategy of the virtual sensor and virtual actuator the reconfigured controller is automatically designed and transmitted to the control station to replace the original control algorithm. In the whole sequence no human interaction is necessary. The main contributions of this paper are the combination of a diagnosis method and a reconfiguration method to perform a completely automated sequence, the implementation of this concept and the evaluation by experiments on a thermal fluid process.","PeriodicalId":251538,"journal":{"name":"2014 European Control Conference (ECC)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128589480","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}

These disturbances can be described with good accuracy by stochastic models. Although methods for the stability analysis of dynamic systems, which are subject to stochastic disturbances, are readily available, they are not widely used in practical applications. Instead, a control design is often performed for a nominal system model, while its robustness is commonly evaluated separately by numerous simulations (e.g. Monte-Carlo techniques) aiming at a quantification of the influence of disturbances. For this reason, methods are presented in this paper which are both applicable to the stability analysis of control and observer structures for ship cranes and to the enhancement of robustness properties by directly accounting for the stochastic nature of disturbances during control design. Suitable simulation results are presented which highlight the applicability of the presented methods for the trajectory control task of ship-mounted boom cranes.","PeriodicalId":251538,"journal":{"name":"2014 European Control Conference (ECC)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129096006","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}

Given a measurable continuous, bounded periodic signal, with non-zero first harmonic in its Fourier series expansion, a dynamic algorithm is proposed which provides an on-line globally exponentially convergent estimate of the unknown period. The period estimate exponentially converges from any initial condition to a neighborhood of the true period whose size is explicitly characterized in terms of the higher order harmonics contained in the signal. It is shown that the converging period estimate can be used to initialize a locally exponentially convergent estimator for the unknown period. Existing results on local frequency estimation of periodic signals are extended in two ways: any initial frequency estimate is allowed without imposing any restrictions on the algorithm design parameters; the exact value of the period is exponentially obtained, provided that the initial conditions for the period estimate are sufficiently close to the true value. When the periodic signal is a biased sinusoid, the unknown frequency is exactly estimated, along with its bias, amplitude and phase from any initial condition, thus recovering a well-known result.","PeriodicalId":251538,"journal":{"name":"2014 European Control Conference (ECC)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114115239","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}

In many schemes, a customer can start and end a journey at different docking stations and is billed according to a set fee structure. However, a given system generally becomes imbalanced due to asymmetry of demand for such “one-way” services across the system and throughout the day, and the resulting cost of employing staff to redistribute the system's vehicles is significant. This paper describes how dynamic customer prices, varying geographically as a function of the current and expected future state of the system, could be used as control signals to improve service rates. Such signals could be communicated to customers using existing ICT infrastructure. We show, using an agent-based model parameterized with historical data from London's Barclays Cycle Hire scheme, that simple proportional price control rules can improve service rates without the need to resort to conventional bike redistribution staff. In addition we analyze the performance obtained and discuss system design issues.","PeriodicalId":251538,"journal":{"name":"2014 European Control Conference (ECC)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116285884","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 the estimation of compressor, gas turbine and combined efficiency are considered. Obtaining performance maps is mainly based on fitting an empirical model to the history of past data together with the understanding of how much new information is contained in newly collected data samples. This amounts to solving a least-squares problem which is formulated as a quadratic program using various constraints. Comparing the actual efficiency to the predicted efficiency by evaluating the previously fitted model, the algorithm decides whether the actual model is accurate enough or a model update is needed. The necessity of having an online model update comes from the fact that the efficiency maps can change due to several factors such as fouling. The algorithm is tested using industrial data from a gas compression station with five gas turbine-driven compressors. The results show the need of online adaptation and that it is possible to accurately predict the different efficiencies using the presented method without excessive model updates. The access to online updated performance maps allows to understand how well the system is performing and gives the opportunity to monitor the efficiency of a specific unit. It is possible to use the adapted performance maps for load sharing optimization with time-varying optimization models.","PeriodicalId":251538,"journal":{"name":"2014 European Control Conference (ECC)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114714900","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}
