Nonlinear systems identification is approached by employing a genetic programming computational tool featuring explicit building block exploitation. The level of adaptation of recurrent model sub-structures is assessed by a fuzzy module. The first contribution of the paper resides in using the fuzzy classification results to reconfigure the cut point selection probabilities of regressor inner nodes, a process called encapsulation. This allows for the second innovation, namely the design of context aware genetic operators capable of protecting the existing instances of fit building blocks and of creating new ones. The computational costs of encapsulation are reduced by employing a novel regressive schema theory - the third and main paper contribution - which assesses the inherent chances of regressor survival. A thorough theoretical support for demonstrating the efficiency of context aware operators in transmitting schema instances over the generations is introduced. The suggested algorithm is experimentally validated in the framework of a complex, industrial, nonlinear subsystem of a sugar factory. © 2011 CACSUK.

In this paper we address the question of "Why is it that a mobile robot, programmed in a certain way and placed in some environment to execute a program, behaves in the way it does?". We present three real world experiments in which we first obtain transparent controllers to express sensor-motor couplings of a mobile robot. We then use these models to analyze the robot behaviour formally;in particular to understand how the sensor readings are related to motor commands, to evaluate the derived controllers from a mathematical point of view and even to predict the behaviour of the robot in untested environments. © 2011 IEEE.

This paper proposes a model to quantify the reliability of web services. Based on their structures, web services can be classified into the following two kinds: atomic web service which calls no other web services and composite web service consisting of atomic web services. The model first evaluates the reliability of atomic web services from the consumers' perspective. After that this paper points out redundancy is a very effective approach to improve the reliability of composite web services. Then the reliability issue of composite web services is discussed. A method of computing the aggregating reliability of composite web services is introduced using the structure information with the assumption that the reliabilities of atomic web services in the composite web services are available. © 2011 IEEE.

This paper presents a procedure for optimization of the switched reluctance drive, in order to achieve required torque-speed characteristics. SRM configuration and characteristics are given, and experimental verification of the modeled characteristic is presented. Genetic algorithm (GA) was used for optimization of turn-on angle, turn-off angle and voltage, which represent basic control inputs. The achieved results suggest that the machine's geometry should be optimized as well. © 2011 IEEE.

We propose a procedure for applying a teaching-learning methodology, where the student's interest is considered a relevant issue. This procedure is based on: a) resources and material available;b) specific classroom, activities;c) external classroom activities, linking the learning process with the real world;d) continuous evaluation. The full process is evaluated from both points of view: teaching and learning. The results obtained allow us verifying the appropriateness of this strategy. © 2011 IEEE.

Grade changes in polyethylene reactors, i.e., changes of operating conditions, are performed on a regular basis to adapt to market demands. In this paper, a dynamic optimization procedure is presented built upon the Modelica language extended with Optimica constructs for formulation of optimization problems. A Modelica library for the Borstar ® multistage polyethylene reactors at Borealis AB, consisting of two slurry and one gas phase reactor, has been constructed. Using ***, a framework to translate dynamic optimization problems to NLP problems, optimal grade transitions between grades currently used at Borealis AB, can be calculated. Optimal inows and grade key variables are shown. © 2011 IFAC.

Robots used in manufacturing today are tailored to their tasks by system integration based on expert knowledge concerning both production and machine control. For upcoming new generations of even more flexible robot solutions, in applications such as dexterous assembly, the robot setup and programming gets even more challenging. Reuse of solutions in terms of parameters, controls, process tuning, and of software modules in general then gets increasingly important. There has been valuable progress within reuse of automation solutions when machines comply with standards and behave according to nominal models. However, more flexible robots with sensor-based manipulation skills and cognitive functions for human interaction are far too complex to manage, and solutions are rarely reusable since knowledge is either implicit in imperative software or not captured in machine readable form. We propose techniques that build on existing knowledge by converting structured data into an RDF-based knowledge base. By enhancements of industrial control systems and available engineering tools, such knowledge can be gradually extended as part of the interaction during the definition of the robot task. © 2011 IEEE.

Human space exploration was given a new boost by targeting again the Moon and the Mars. Besides the USA, China, India and Russia announced their progressive plans to put astronauts on orbit and beyond in the next decades. The continuous development of robotic technology should lead to the advancement of automated technology, including space medicine. Telesurgery has already proved its effectiveness through various procedures on Earth, and it has the potential to provide medical assistance in space. Space agencies have already conducted numerous experiments and developed various setups to push the boundaries of teleoperation. Different control schemes have been proposed and tested to facilitate and enhance telepresence and to ensure transparency, bandwidth and latency-tolerance. This paper focuses on the modelling of a generic telesurgery setup, supported by a cascade control approach. The minimalistic models were tested with classical and fuzzy PID control options to provide a simple, universal and scalable solution for the challenges of telesurgery over large distances. In our simulations, the control structures were capable of providing acceptable performance indices up to 2 seconds of roundtrip delay, which is a promising result towards the support of future teleoperational missions.

This paper presents the results obtained by visual predictive control laws in real-time visual servoing architectures. A key role when designing a stable image based control law is played by the visual features, and thus both points and image moments were considered and their performance revealed. A 6 d.o.f manipulator robot with an eye-in-configuration is used to design a visual servoing architecture and realtime implementation using Matlab is described. The results of different experiments for planar static objects are presented and discussed. For establishing the performance of visual predictive control laws a comparison with classical image based control laws is conducted. © 2011 IEEE.
