The question is addressed whether metric properties are preserved under this non-linear operator that maps input signals to spike trains, or, synonymously, event sequences. By measuring the distance between input signals by means of Hermann Weyl's discrepancy norm and applying its discrete counterpart to measure the distance between event sequences, it is proven that LIF approximately preserves the metric. It turns out that in this setting, for arbitrarily small thresholds, LIF is an asymptotic isometry.","PeriodicalId":411767,"journal":{"name":"2016 Second International Conference on Event-based Control, Communication, and Signal Processing (EBCCSP)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114813545","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 process model can estimate process control parameters when a measurement fails or when lab sampling is used as a control parameter. Wireless control is another case in which event-based MPC operation, including both slow sampling and randomness, is required. Wireless actuators connected directly to the MPC outputs or through PID loops with wireless actuators and measurements add a significant sophistication to the system. MPC wireless operation has been validated on a Dividing Wall Column (DWC) process which can provide potentially huge savings in energy and capital cost compared to a conventional column design. In the installation at the University of Texas, WirelessHART transmitters take many of the process measurements used in control. This paper details event driven wireless MPC operation and design and discusses the application challenges illustrated by the test results.","PeriodicalId":411767,"journal":{"name":"2016 Second International Conference on Event-based Control, Communication, and Signal Processing (EBCCSP)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127221405","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 strives to virtualize the common elements found within it and integrates them transparently to an existing Building Management System (BMS), along with existing infrastructure. Thanks to this integration layer, the building management and its control intelligence are completely agnostic to the operations of that virtualization engine. A unique feature of this engine is its micro-treading based core. The latter permits a highly optimized, pseudo-concurrent simulation of hundreds building elements (e.g. loads, sensors, storage, generation, user, etc) in a lean, commodity hardware. Primary virtualization aim is the real-time power data of a SB for the purpose of energy management and Smart Grid connectivity. Moreover, energy optimization and financial studies can be conducted proactively, before committing to costly physical infrastructure investments.","PeriodicalId":411767,"journal":{"name":"2016 Second International Conference on Event-based Control, Communication, and Signal Processing (EBCCSP)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115313923","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 control system objective is to maintain the desired humidity level, keeping the water usage as low as possible. The event-based control scheme uses a crop transpiration model and a water content virtual sensor to trigger the irrigation system events. In such a scheme, the event-based controller determines the volume of water required to compensate for the irrigation system disturbances. Simulation experiments were performed to analyze the behavior of the designed system and to study the water supply dynamics to the substrate and subsequent drainage and evaporation. The resulting control system is able to adapt the actuation rate to the state of the plant providing the efficient way of water consumption. The obtained results show that application of proposed event-based approach for the greenhouse irrigation system allows us to improve the control performance and to reduce the water usage being an important issue in intensive agriculture. The improved control performance is obtained due to event-based approach and the inclusion of information about the plant dynamic response for water supply and transpiration effect.","PeriodicalId":411767,"journal":{"name":"2016 Second International Conference on Event-based Control, Communication, and Signal Processing (EBCCSP)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127377604","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 benchmarks can be used to compare the performance of continuous-time, discrete-time, and various event-based controllers with regard to for instance disturbance attenuation, control effort, and average sampling or actuation rates. They can also be used to evaluate heuristic event-based PI(D) controllers and see how their performance compare to each other and to regular sampled-data control.

The principle of the conversion process in SA-TDC consists in successive delaying the events defining a start and a stop of the input time interval by the use of binary-weighted delays. The paper is focused on optimization of particular components of the SA-TDC architecture with a single set of delay lines in order to reduce differential (DNL) and integral (INL) nonlinearities. In particular, the paper contribution is an improvement of time resolution of the converter from 25 ps to 12.5 ps (i.e., by one extra bit) in 180 nm CMOS technology through enhancements of design of circuit components which results in a reduction of conversion errors.","PeriodicalId":411767,"journal":{"name":"2016 Second International Conference on Event-based Control, Communication, and Signal Processing (EBCCSP)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126680486","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 control feedback loop is closed by means on an estimator based on an Unscented Kalman Filter (UKF) with event-based updates. The estimator requests measurements from a camera sensor only when it needs them. The measurements are triggered by an adaptive condition on the pose estimation error covariance matrix. The main advantage of this method is that it allows for reducing the volume of CPU intensive image processing which is characteristic of these kind of sensors, as well as avoiding the unnecessary overload of the communication channel. The main contribution of the current work is the actual implementation with a P3-DX robotic unit remotely controlled.
