International Symposium on applied Computational Intelligence and informatics ( SACI)

作者： Marius-Florin Crainic Stefan Preitl Dept. of Automation and Applied Informatics “Politehnica” University of Timisoara Timisoara Romania

Due to the continuous technological progress, life becomes more comfortable. The fact is also valid for robotized technological lines where workers have to command and control the movement of robots and robotic arms. In this context, the paper presents an alternative way of controlling a mechanical Rv-2AJ robot arm, applicable mainly for locally controlled robots. The main characteristics of the application are an ergonomic operating mode, video and tactile feedback control, low price; the application can have also a didactical purpose, and can offer a highly useable material for mechatronic laboratories for students teaching.

Facial expression recognition is an important research domain in developing human-machine relations. This paper proposes a facial expression recognition system. This system is built using Constrained Local Models to fit the shapes on a face image and on Support Vector Machines (SVMs) to detect the face expressions. Different SVM architectures and trainings have been used including applying outliers filtering to obtain better recognition rates.

This paper proposes data-driven Model-Free Adaptive Control (MFAC) algorithms for a Multi Input-Multi Output (MIMO) twin rotor aerodynamic systems. The azimuth and pitch position control are carried out using a MIMO control system structure with two control loops, one for each axis of motion. A set of experimental results on laboratory equipment is given to show the ability of the MFAC algorithms to control the mechanical ensemble even without decoupling and in spite of disturbances.

This paper sets the basis of a robot collaborative application framework that is able to perform basic interactions with a human partner, namely patrol and monitor a designated area, followed by interaction with a human participant when this is detected. The application is developed using an adaptation of ROS to Corobot robot and image processing techniques that involve OpenCV face detection.

In this paper, a nineteen level dodecagonal voltage space vector structure is proposed for the first time, by cascading two asymmetric three level inverters with isolated H-Bridges. The dodecagonal structure is made possible by proper selection of DC link voltages and switching states of the inverters. The proposed scheme retains all the advantages of multilevel topologies as well the advantages of dodecagonal voltage space vector structure. A generic and simple method for calculation of PWM timings is proposed. Also, a new method of switching technique is proposed, which ensures minimum switching while maintaining the linearity between modulating signals and the output phase voltages. Extensive simulation and experimental results have been presented for validation of the proposed concept. © 2014 IEEE.

Telesurgery means the remote application of interventional medical techniques;a concept that is currently widely practiced around the world for short distance through master-slave robot systems. The concept has the potential to service long distance telesurgery as well. However, this requires the effective handling of communication latency. The current paper suggests a fuzzy control solution for telesurgical applications aiming at the alleviation of the disturbing effects of large latencies with the concept of remote surgical robotics. The fuzzy control solution is supported by a cascade control system structure with two proportional-integral-derivative (PID) controllers in the inner and outer control loops and designed by Kessler's Extended Symmetrical Optimum empirical criteria. The PID controller in the outer loop is next replaced by Takagi-Sugeno-Kong PID-fuzzy controllers which combine several separately designed PID controllers. The combination of separately designed PID controllers and the modal equivalence principle are expressed as a design and tuning method of the Tagaki-Sugeno-Kong PID-fuzzy controllers. © 2011 IEEE.

HOLONIC FAULT-TOLERANT CONTROL OF NETWORKED ROBOT-VISION ASSEMBLY STATIONS

IFAC Proceedings Volumes 2007年第2期40卷 42-47页

作者： Theodor Borangiu Luis Manuel Tomas Balibrea Florin Daniel Anton Nick Ivanescu Silvia Tunaru Anamaria Dogar Silviu Raileanu University Politehnica of Bucharest Dept. of Automation and Applied Informatics Universidad de Murcia Facultad de Economia y Empresas

The paper describes a networked fault-tolerant assembly system of job shop type containing multiple robotized stations operating under visual control. During the assembly process, the products are identified, located, qualified, and controlled by analyzing images from virtual cameras associated to stationary- and arm-mounted cameras. The holonic control architecture is formed by the following types of entities: a Global Assembly Scheduler generating Order Holons, a dual layer of Material Handling (Robot) Holons and Sensory Holons, and a System Monitoring & Database entity. These elements are embedded in a 3-layer computing & control structure, and interconnected by a 4-fold fault-tolerant communication network keeping track of assembly job execution. Implementing issues and experimental results are reported.

INTERACTIVE LEARNING OF SCENE-ROBOT MODELS BASED ON AI TECHNIQUES

IFAC Proceedings Volumes 2006年第3期39卷 205-210页

作者： Theodor Borangiu Florin Anton Silvia Tunaru Anamaria Dogar Nick Ivanescu University Politehnica of Bucharest Dept. of Automation and Applied Informatics 313 Spl. Independentei sector 6 Bucharest 060032

Intelligent image processing blurs the distinction between Guidance Vision for Robots (GVR) and Automated Visual Inspection (AVI) applications. The paper presents AI techniques for interactive learning of scene-object models by feature descriptions of part flows. Robot grippers are modelled by fingerprints for ***collision-free part access. The parameters of the vision models are remotely created by a Server application which accepts simultaneous connections over LAN/Internet with multiple Clients – executing on IBM PC robot terminals integrated in flexible, networked manufacturing structures. Experimental results are reported for cluster and pattern construction for part recognition.

The aim of this paper is to present a control scheme for controlling the temperature in a slab which is not directly measurable. The process can only be controlled by manipulating the ambient temperature (boundary control). We describe the physical process and derive its (distributed) transfer function (DTF). The sensitivity of the model for one of the parameters is analyzed. We describe a model reduction technique which provides an accurate approximation of the distributed transfer function. Based on the reduced order model we present an Internal Model Control (IMC) scheme applied to the heat process and analyze the *** order model
