A new middleware solution called Network Adaptive Deadband is presented, to relate network status and NCS status. Network Adaptive Deadband relates a TCPFriendly flow control algoritm with the deadband filtering solution for NCS data. Based on selected design parameters, an experimental methodology is studied to find the relationship between network consumption and deadband. Application and transport agents for NS2 are developed to simulate a granty crane teleoperated platform and a mass-spring NCS. Results illustrate the succesfull share of public network resources.","PeriodicalId":149864,"journal":{"name":"18th Mediterranean Conference on Control and Automation, MED'10","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121012993","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 main difficulty in controlling these systems stems from their non linear nature as their switched circuit topology entails different modes of operation. Based on the Takagi-Sugeno Fuzzy Modelling approach with the duty ratio as premise variable, the converter model can be derived in every operating point. For each local model, a state feedback based control law is designed by the way of the PDC (Parallel Distributed Compensation) and LQR (Linear Quadratic Regulator) techniques. The nonlinear feature of the transfer function relating the output voltage to the duty ratio, caused by the inductor ESR, is handled by a Piece wise Affine (PWA) approximation using TS method of fuzzy inference. Finally, simulation results from a PWM Buck-Boost converter illustrate the efficiency of the proposed approach.","PeriodicalId":149864,"journal":{"name":"18th Mediterranean Conference on Control and Automation, MED'10","volume":"82 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113970393","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 is mainly due to a loss of friction between tire and road. Many of these accidents could be avoided by introducing ADAS (Advanced Driver Assistance Systems) based on the detection of loss of tire/road friction. Friction (more specifically the maximum coefficient of friction) which is a parameter of tire/road interaction, mainly depends on the state of the road (dry, wet, snow, ice) and is closely related to the efforts at the tire level. In this paper, we propose, a new method for the estimation of the maximum tire/road friction coefficient, to automatically detect possible state of loss of friction which result in an abrupt change on the road state. This method is based on an iterative quadratic minimization of the error between the developed lateral force and the model of tire/road interaction. Results validate the application of the method.","PeriodicalId":149864,"journal":{"name":"18th Mediterranean Conference on Control and Automation, MED'10","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122694734","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 LQ-controller is developed on the basis of the catalytic reactor with unidirectional flow. The controller is formulated to keep the distribution of the temperature along the axis of the reactor at stationary state by using the fluid flow velocity. We study the application of the controller on the catalytic reactor with reverse flow operation. We take advantage of the two-time scale characteristic of catalytic tubular reactors to develop a controller that requires only the measurement of the temperature along the axis of the reactor. Using the infinite dimensional state space, a state LQ-feedback operator is computed via the solution of a Riccati differential equation. The developed controller is tested numerically for the catalytic combustion of lean methane emissions in CFRR unit and implemented for a reactor configuration at the CANMET Energy Technology Centre Varennes, Quebec, Canada, and currently experimental tests are underway.","PeriodicalId":149864,"journal":{"name":"18th Mediterranean Conference on Control and Automation, MED'10","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122943549","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 concrete type of robot we studied is a robotic scrub nurse (RSN) for microsurgery. In microsurgery the surgeon works behind a microscope and must maintain field of view as much as possible. The task of managing and delivering instruments to the surgeon rests with the scrub nurse. During our attempt to design a robot which could automate this delicate but repetitive task we have identified the robot interface to instruments and human subjects as the essential component and have made that the central topic of our work. Special attention was paid to the robot-human interface at the haptic level. To that end we designed and evaluated a shape conforming grasp mechanism to act as a soft touch interface constantly adapting to the human touch. Such approach is uncommon in the robotic industry where per- task adapter-style exchangeable grasping mechanisms are mounted on the robot for each run. While industrial robots deal with few instruments and must lift heavy weights, this problem domain contains hundreds of instruments and prohibits any type of crushing or cutting movements. Our results show that the application of universal soft touch grippers is justified in environments where humans interface robots.","PeriodicalId":149864,"journal":{"name":"18th Mediterranean Conference on Control and Automation, MED'10","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132616924","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 successful implementation of MPC involves the setting of a considerable number of parameters which must be appropriately tuned. Despite a number of publications on MPC tuning, there is a lack of a systematic approach that relates MPC tuning to linear control theory. In this paper, a systematic tuning of the prediction horizon, the control horizon and the penalty weights is discussed such that desired closed-loop pole and zero locations result as long as the constraints are not active.
