This paper highlights the differences between a simple sensorless method and an adaptive flux and speed observer for a five-phase induction motor control. The drive is controlled using space vector modulation direct torque control (DTC- SVM) approach. The power measurement used for speed computation is simple, with a minimum processor time and memory, and relatively robust against parameters variation when compared with the adaptive observer based approach. Simulation verification and real time implementation are presented in the paper.

Abstract The paper considers design of Robustly Feasible Model Predictive controller which achieves recursive robust feasibility of the generated control actions when applied to nonlinear network systems with state constraint under bounded disturbances. The optimizing control algorithm with safety zones modifying the model based state constraints is derived to achieve recursive robust feasibility. Its performance is illustrated by application to optimizing control of hydraulics in Drinking Water Distribution System example. Copyright © 2011 IFAC

Emergence of Web 2.0 technologies became a trigger for a revolution that goes far beyond the Web. For an average student Web was transformed from a steady, accessible source of information into a place of action and viable exchange of knowledge a kind of a virtual classroom. Students started to look for experience and a touch to reality online, and this is where remote laboratories come in place. Such laboratories became an inevitable need in electrical and computer engineering courses dealing with microcomputers. This paper presents an overview of available architectures of microcomputer laboratories used today and addresses their most important limitations. Moreover, an important extension of such architecture is proposed allowing support for remote Wireless Sensor Network (WSN) laboratory. Different aspects of compatibility between microcomputer laboratories and WSNs have been examined to allow creation of an general extension model. With additional effort and adaptation, WSN nodes may serve remote clients as an economic and accessible microcomputer laboratory providing invaluable hands-on experience and a motivation for a course using it. © 2011 MIPRO.

This paper presents a simple and novel sensorless scheme for five-phase induction motor control. The power measurement is used for speed computation. The drive is controlled using direct torque control (DTC). Speed sensorless control scheme is tested under speed variation and load changes. The control method is simulated and implemented in real time on the DS1103 board.

A direct and an indirect adaptive fuzzy state feedback approximation are considered for a class of nonlinear systems. In this work the control system consists of sliding- mode control and an adaptive fuzzy logic control. An adaptive fuzzy approximation plays a dominant role to maintain the c1osed- loop stability. The sliding- mode control is inserted to handle the influence of external disturbance and fuzzy approximation error instead of upper bound of the plant. In this work a stable direct and an indirect fuzzy adaptive sliding-mode controller for a class of nonlinear system are developed. The developed algorithms guarantee the asymptotic stability of the closed-loop system. Two simulation examples are given to illustrate the performance of the proposed methods .computer simulation results confirm that effect of both external disturbance and fuzzy approximation error can be compensated by the developed methods. A comparative study is also conducted for both algorithms. ©2010 IEEE.

This paper describes the design and fabrication of an intelligent Irrigation control system that allows intelligent control of the water applied to the field at right amounts and times. The system should have the capabilities to measure the water content in the soil so water can be applied as needed. The WATERMARK soil moisture sensor based on the measurement of the soil tension will provide the measurement of the water content. The system measures the soil tension, soil temperature and rain status and records the data in a file for future reference. It will apply water to field if a certain level of soil water tension is reached. This intelligent Irrigation control system is suitable for universities, research centers and farms where a control of the soil water content is required. The system can be used to study the water requirements for crops so irrigation can be scheduled efficiently.

International Conference on Emerging Technologies and Factory Automation (ETFA)

The IEC61499 is an open standard for distributed control and automation. The interface between control software and hardware or communications is achieved by means of the so-called Service Interface Function Blocks (SIFB). This paper presents the guidelines to build communication SIFBs based on the emerging OMG DDS (Data Distribution Service) middleware. This specification implements in a very efficient way the Publisher/Subscriber paradigm providing significant QoS configuration possibilities. These characteristics make DDS suitable for implementing the communications among time-critical devices. By using these DDS-SIFBs within IEC61499 code generation tools, the designers of the distributed applications will be allowed to use this powerful technology in the new distributed applications.
