The control objective for this type of systems is often a trade off between the deviation from the reference and the number of switches (weariness energy efficiency etc.). For such systems a steady state solution might never be attained, but rather the optimal behavior might be constituted by a limit cycle. In this paper we consider the problem of finding and controlling the system towards an optimal limit cycle. A low complexity approach giving a suboptimal solution, and avoiding the above problems will be proposed.","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":"128455508","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 contains two remote web cameras and an onboard sensor with three gyroscopes and three accelerometers. The camera positions are unknown. The gyroscope and accelerometer measurements have unknown random bias with a slow trend. For estimation of these parameters an adaptive filtering system with the extended Kalman filter is developed. Tuning of the filter parameters is made online by minimization of the high frequency part of the helicopter velocity estimate. A new method is also developed for smoothing of the big oscillations forced by rotation of the main rotor that appear in the gyroscope measurements of the angular velocity. The method is based on equations from the helicopter motion model that give a relation between linear accelerations and the Euler angles estimated by integration of the angular velocity measurements.","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":"129912129","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 be more precise, sensible heat exchange characterized by room sensible heat factor (RSHF) responses to the change in temperature; whereas latent heat exchange characterized by apparatus sensible heat factor (ASHF) responses to the variation in humidity. The problem of temperature control is to assess not only the sensible heat transfer, resulting from the mismatching between RSHF and ASHF while the system attains its equilibrium state, but also the extra cooling load while the system is on the transient stage. Simulation results show a good agreement that the car compartment condition will converge into the comfort zone defined by ASHRAE Standard, regardless of initial conditions.","PeriodicalId":294950,"journal":{"name":"2009 IEEE Control Applications, (CCA) & Intelligent Control, (ISIC)","volume":"31 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":"123487198","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 is shown that the upper and lower bounds of limited synchronization error are proportional to the maximum coupling signal rate and inversely proportional to the minimum information transmission rate of network communication links (minimum channel capacity). The results are illustrated by example of synchronization in the network of Chua systems coupled via communication links with limited capacity.","PeriodicalId":294950,"journal":{"name":"2009 IEEE Control Applications, (CCA) & Intelligent Control, (ISIC)","volume":"20 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":"114316517","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}

FHMs resemble Takagi-Sugeno-Kang (TSK) fuzzy models in general, however have some advantages. FHM is an inherently nonlinear model and can capture all the nonlinearities of the system. On the other hand there are some systematic approaches to design and analysis such models. The synergy between Artificial Neural Networks (ANN), which are notorious for their black-box character, and fuzzy logic proved to be particularly successful. Such a synergy allows combining the powerful learning-from-examples capability of ANNs with the high-level symbolic information processing of fuzzy logic systems. The offered network is used to obtain the parameters of the plant from input-output data. It is shown that there is a unique transformation from the proposed network to hyperbolic model of the plant and vice versa. Parameters of the fuzzy model can be obtained from weights and biases in trained network. Boiler-Turbine system is considered as a case study to show how the proposed ANN can be used to extract the fuzzy model. The obtained model is validated by some input-output data provided from the reference model. Simulation results proved the effectiveness of the offered neural network in extracting the fuzzy model of the plant.","PeriodicalId":294950,"journal":{"name":"2009 IEEE Control Applications, (CCA) & Intelligent Control, (ISIC)","volume":"134 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":"116491881","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}
