This paper presents a sewing cell based on an industrial sewing machine, and with two robots controlling the sewing operation in real-time. The software architecture and the communication structure are presented. Widely available software and hardware technologies were used to build a highly flexible system for operation and control prototyping. This paper focuses on analyzing the real-time characteristics of the control system. Experiments were conducted to measure the delays in different parts of the system in order to gain an understanding of the real-time performance and to show that the chosen system is capable to make use of the robot's high update frequency and low tracking delay.

pH neutralization is a difficult process to be controlled due to the nonlinear and time-varying process characteristics. Model Predictive control appeared in industry as an effective means to deal with multivariable constrained control problems. This paper does the study of the pH neutralization process of a weak acid - strong base system using a neural network model predictive control technique. The simulation results are analyzed for step and random acid disturbances, which shows that the controller controls the pH within the required limits with less mean square error.

This paper describes the no-lineal model, and attitude Robust control of a Quadrotor MIMO system (UAV). The dynamic model of the UAV is transformed into a LTI system and approximated by a SISO system due to the low coupling among the canals of the system. The unknown model parameters have been taken of the system implemented in the Center for Research and Advanced Studies of the National Polytechnic Institute (CINVESTAV). Finally, robust controller has been designed using H∞ theory. The effectiveness and performance of the proposed control approach have been proved in simulation using MATLAB. © 2013 ieee.

Limited research has been conducted in utilizing telemedicine to promote upper and lower limb rehabilitation using remotely controlled home-based ergometers. The goal of this study was to develop and assess a telerehabilitation system supporting internet-controlled home-based cycling exercise. We designed an interface to control cycling speed of an ergometer from a remote server via Internet. The evaluation of the interface included consecutive transmission of 7 different cycling speed levels, each level of 2-minute duration. Overall, the mean difference between remotely setup and actual cycling speed was 0.002+/-0.03 miles/hour. Our evaluation demonstrated high fidelity of the proposed system and reliability of controlling individualized exercise prescription for home-based cycling equipment via Internet.

Nowadays privacy in ambient system is a real issue. Users will have to control their data more and more in the future. Current security systems don't support a strong constraint: policy writers are non-technical users and not security experts. We propose in this paper to use Decision Support techniques and more specifically Multi-Criteria Decision Analysis in the process of authorization policy writing. This research area provides techniques to inform and assist non-technical users to write their own authorization policies following the paradigm of Attribute-Based Access control.

In today's world, there is a strong need for sharing big data for collaboration. However, privacy and security remains a barrier especially when dealing with massive amounts of data in the Cloud. In particular, there is a growing need for the data owner to gain better access control over their data. The data owner should be able to specify how their data should be viewed, copied and modified. A dishonest authorised user may illegally redistribute the data to other friends and/or colleagues who don't have the relevant access permissions. In this paper, we address these issues by introducing the idea of SafeShare which controls how data can be accessed and used. SafeShare encapsulate data in self-controlling objects (SCO's) and additionally monitors operations of the user. We demonstrate that our SafeShare system will prevent the user from carrying out any illegal operations including illegal redistribution of data. In addition, we add another level of security on the SCO's by adding a log file and hash for better auditing control.

Permanent-magnet synchronous motor (PMSM) are mostly used in high-performance industrial servo applications in which torque smoothness is necessary. The main disadvantage of PMSM is torque ripples, which induce speed pulsations that deteriorate the performance of drives particularly at lower speeds. This paper propose the proportional plus integral controller (PI)working in transient state in parallel with Iterative learning control (ILC) working in steady state with Space Vector Pulse Width Modulation (SVPWM) to suppress the speed ripples in PMSM driven by field oriented control. The speed controller compares the reference speed with actual speed, and thus produce the reference current iq ref value which in turn reduces the speed error. According to iq ref value SVPWM pulses are produced and given to the three phase voltage source inverter. The advantages of the proposed method for speed ripple reduction is designed, analysed and simulated using simulink library in MATLAB R2009a. The results obtained from simulation show the significant reduction in speed ripples using proportional plus integral controller (PI) plug in Iterative learning control (ILC) with Space Vector Pulse Width Modulation (SVPWM). This method shows better speed ripple reduction in comparison with the conventional method. © 2013 ieee.
