Developing dynamic control-oriented models for such systems represents a crucial tool for the future design of software sensors and model-based control strategies. To this end, this work presents a MFC process control-oriented model obtained by combining fundamental equations based on mass and electron balances with equations describing an equivalent electrical circuit. Such model accounts for the double layer capacitance effect and complex nonlinear dynamics observed during pulse-width modulated operation of the external resistance and therefore, it is able to describe the observed biological or long-term dynamics as well as the electrical or short-term dynamics. The parameter estimation for a simulation and a prediction MFC process control-oriented model is here described.","PeriodicalId":127957,"journal":{"name":"22nd Mediterranean Conference on Control and Automation","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124292093","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}

This technique is called direct control of fuzzy power (DPCF). The objective of this paper is to replace both hysteresis controllers that role for setting the active and reactive power by a single fuzzy controller which adjusts both active and reactive power at the same time. The aim of this work is to eliminate the harmonic currents and therefore reduce the total harmonic distortion of the line current and improve the power factor. This DPCF is tested by simulation studies on a three-phase PWM rectifier.","PeriodicalId":127957,"journal":{"name":"22nd Mediterranean Conference on Control and Automation","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129224603","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}

Based on the use of the notations and properties of the tensor product, the nun-redundant state formulation and the polynomial description of the studied systems, the derived reduced model is also characterized by a polynomial discrete time state equations truncated at the third order. An important feature of this approach is that the resulting reduced order model preserve the form of the original high order systems and can be used for further analysis and design with less computational cost. An illustrative example is considered to investigate the accuracy and efficiency of the proposed approach.","PeriodicalId":127957,"journal":{"name":"22nd Mediterranean Conference on Control and Automation","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128705076","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}

A potential-field approach is used to generate a desired velocity for each UAV which ensures that the team of UAVs can perform formation and reconfiguration, avoid inter-vehicle collision as well as track a specified virtual leader. Each UAV is controlled to track its desired velocity subject to dynamic constraints. The proposed feedback control is robust against error disturbances due to dynamic constraints and measurement noise. A formation flight test of three quadrotor UAVs demonstrates the effectiveness and robustness of the proposed formation control strategy.","PeriodicalId":127957,"journal":{"name":"22nd Mediterranean Conference on Control and Automation","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116192439","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 enforce coordination between entities in a network, they need to share information over this network in order to reach a consensus. We propose an approach to apply a consensus-based control protocol to a network of max-plus linear non-autonomous dynamical systems. In this framework the networked control system is required to achieve consensus on the asymptotic growth rate of the outputs. This leads to a synchronized and stable networked system. The conditions needed to achieve consensus and the consensus value are investigated.","PeriodicalId":127957,"journal":{"name":"22nd Mediterranean Conference on Control and Automation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116202598","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 method is based on designing a nonlinear observer using State Dependent Differential Riccati Equation (SDDRE) and a nonlinear model of the 5MW wind turbine. The fault detection system is designed and optimized to be most sensitive to system faults and least sensitive to system disturbances and noises. The comparison of system outputs with nonlinear observer outputs are given to demonstrate good estimation performance. The residual generator based on the nonlinear observer is also employed to develop a monitoring system. Simulation results presented to illustrate that the proposed method is robust and can detect and isolate a fault or multi-faults in sensors of the wind turbine.","PeriodicalId":127957,"journal":{"name":"22nd Mediterranean Conference on Control and Automation","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126925183","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}

Thermal feedback, as a part of haptic feedback can assist in object identification, or in the creation of a more complete haptic signature of a given object. However, the heat exchange occurring between a fingertip and a given touched object is affected by the contact conditions. This paper proposes a Particle Swarm Optimization (PSO) algorithm for identification of thermal contact resistance. This resistance is estimated for variable force Hand/Object Interaction using a thermal model describing the heat exchange.

Here, the hovercraft robot model is considered. The controller is designed after transformation the vehicle equations of motion. The main feature of this controller is that it can be used both for fully actuated and underactuated systems. This feature arises from the fact that the dynamics of the vehicle is taken into consideration. The stability of the designed controller is demonstrated based on a Lyapunov method. The controller can be used, in general, for various moving systems as unmanned underwater vehicle, hovercrafts or airships.
