This paper, we propose a new design of linear descriptor discrete time mechanical system control law by using model following control system (MFCS). In previous studies, a method of MFCS was proposed by S. Okubo [11[2]. In this paper, the method of MFCS will be extended to discrete time descriptor mechanical system. The bounded property of internal states for control system is given and utility of this control design is guaranteed. In this case, a new criterion is proposed to ensure that internal states are stable.

The modeling of needle insertion into tissues is important for simulation of this procedure and for robotic technologies applied to percutaneous therapy. In this article, we present a first attempt to develop a general force model for the needle insertion throw different tissue layers (skin, fat and muscle) to reach an internal organ (the liver, for instance) with objectives of control, looking for an optimal (less invasive and more accurate) puncture task. The forces are divided into three parts: stiffness, a nonlinear model;friction, a modified Dahl model;and cutting, a constant for a given tissue. Results show that the overall shape of forces presents the main phases of a needle insertion through several tissue layer.

In a recent IEEE Transactions on Automatic control article, Jadbabaie et al. provides a theoretical explanation of the discrete-time model of groups of mobile autonomous agents raised by Vicsek et al. in 1995. In their paper Jadbabaie et al. established conditions given in terms of neighbor graphs for coordination of agents and provided that these agents are periodically linked together This paper sharpens this result by showing that coordination will be reached under a very weak condition that requires all agents are finally linked together The theorems in this paper show that convergence will be attained if these neighbor graphs are finally linked together This condition is also strictly weaker than the one Jadbabaie et al. desired. An example is provided that illustrates the soundness of the theorem.

Most existing patch-based denoising methods are based on fixed size patch and fixed range of neighborhood, while producing state-of-the-art denoising results, the quality of the algorithm is significantly dependent on patch size. Suppose that patch size is related to image pattern, a structural adaption method for the selection of patch size is proposed in this paper. Due to the mutual similarity between the training samples, the simulation results illustrate the original approach can be effectively improved by adopted this method.

Session 2 includes 110 papers selected from 2011 3rd international asia conference on informatics in control, automation and robotics (CAR 2011), held on December 24-25, 2011, Shenzhen, China. As we all know, the ever growing technology in robotics and automation will help build a better human society. This session will provide a unique opportunity for the academic and industrial communities to address new challenges, share solutions, and discuss research directions for the future. robotics research emphasizes intelligence and adaptability to cope with unstructured environments. automation research emphasizes efficiency, productivity, quality, and reliability, focusing on systems that operate autonomously. The main focus of this session is on the autonomous acquisition of semantic information in intelligent robots and systems, as well as the use of semantic knowledge to guide further acquisition of information.

The present book includes a set of selected papers from the seventh "internationalconference on informatics in control automation and robotics"(ICINCO 2010), held in Madeira, Portugal, from 15 to 18 June 2010. The conference was organized in three simultaneous tracks: "Intelligent control Systems and Optimization", "robotics and automation" and "Signal Processing, Systems Modeling and control". The book is based on the same *** received 320 paper submissions, not including those of workshops or special sessions, from 57 countries, in all continents. After a double blind paper review performed by the Program Committee only 27 submissions were accepted as full papers and thus selected for oral presentation, leading to a full paper acceptance ratio of 8%. Additional papers were accepted as short papers and posters. A further refinement was made after the conference, based also on the assessment of presentation quality, so that this book includes the extended and revised versions of the very best papers of ICINCO *** to high quality standards is a major concern of ICINCO that will be maintained in the next editions of this conference, including not only the stringent paper acceptance ratios but also the quality of the program committee, keynote lectures, workshops and logistics.
