the present book includes a set of selected papers from the 5th "internationalconference on informatics in controlautomation and robotics" (icinco 2008), held in Funchal-Madeira, Portugal, 11-15 May 2008. the conference was organized in three simultaneous tracks: "Intelligent control Systems and Optimization", "robotics and automation" and "Systems Modeling, Signal Processing and control". the book is based on the same structure. the purpose of this conference is to bring together researchers, engineers and practitioners interested in the application of informatics to control, automation and robotics. informatics applications are pervasive in many areas of control, automation and robotics, and this conference intends to emphasize this connection, therefore, most papers highlight applications of Information Technology (IT) in these areas and present ideas on how to solve problems using IT, both in R&D and industrial applications. A diversity of papers are included in the book, ranging from papers describing advanced prototypes, systems, tools and techniques to papers presenting surveys indicating future directions.
A new algorithm to improve the 3D positioning for low cost mobile robots is presented. the core of the algorithm is based on a Finite State Machine (FSM) which estimates the 3D position and orientation of the robots, ...

Model-based approaches are used for testing and diagnosis of automation systems (e.g. (Struss and Ertl, 2009)). Usually the models are created manually by experts. this is a troublesome and protracted procedure. In this paper we present an approach to overcome these problems: Models are not created manually but learned automatically by observing the plant behavior. this approach is divided into two steps: First we learn the topology of automation components, the signals and logical submodules and the knowledge about parallel components. In a second step, a behavior model is learned for each component. Later on, anomalies are detected by comparing the observed system behavior withthe behavior predicted by the learned model.
the problem of two-player pursuit-evasion games with unmanned aerial vehicles (UAVs) in a three-dimensional environment is tackled. A game-theoretical framework is presented, enabling the solution of dynamic games in ...

In this article, a 6 Degree-of-Freedom (DOF) parallel manipulator, actuated by Pneumatic Artificial Muscles (PAMs), is being presented. Incorporated in a two Stewart Platform-based design, the novel manipulator's motion capabilities are being examined through kinematic analysis, while the open-loop operation characteristics and performance of the manipulator's control via a multiple PID-based scheme are being experimentally evaluated.

Nowadays in the reality of the market economy all industries must be competitive. To maintain their market positions, companies continuously reduce the manufacturing costs, while simultaneously improving the quality, reliability, aesthetics, modernity and durability of products. To achieve such a goal, appropriate methods of production management and optimization are required, which is impossible without the implementation of automatic control and robotics into process technologies. When troubleshooting a communications system (such as machines controlled by industrial networks) under operation conditions, engineers or technicians try to use some standard format to come to a quicker solution. Industrial communications system do not always follow the tried and tested rules (1), which previously worked with hardwired inputs and outputs. the rules (tested in laboratory and industrial environments) have some affinities discussed in this paper.

Implementation of active control has much potential to contribute to the creation and construction of innovative structures. this paper summarizes recent research of the authors that is the study of biomimetic control solutions regarding balance and locomotion of robotic systems. A first goal of the work consists in identifying solutions necessary to balance the individual systems. Research has been focused both on systems with a single foot, but also on biped, tripods, quadrupeds, hexapods and octopods. Static balance is achieved by a proper mechanical design (Bizdoaca and Petrisor, 2009), but also by a corresponding load / tensioning actuators systems that can compensate for inertial elements that can lead to system stability limit. theoretical studies have been focused on developing an efficient stepping algorithm in environment with strong uncertainties, known as SSTA algorithm. the article present a series of experiments made with servo actuated and smart actuated (based on shape memory alloy, especially) walking biomimetic structures.

Due to seeker delay and coupling with body motion, a strapdown seeker has not been widely used for missiles though it makes the missile cost cheaper. In this paper, a homing loop design based on PID controller for missiles with a strapdown seeker is suggested. the PID controller produces body rate command, instead of estimating line-of-sight(LOS) rate for the proportional navigation guidance. Stability analysis for linear homing loop has been done to select controller gains. the performance of the designed terminal homing loop for a small tactical missile against a moving target, where the missile's strapdown seeker includes uncertain image processing delay, is verified through full nonlinear 6-DOF simulations.
