In this paper we present a robust and reliable system for interaction with mobile devices using dynamic hand gestures. While other approaches rely on remote computation our system is wearable, lightweight and unobtrusive. It is usable in industrial settings where touch-based interaction is inconvenient and resource efficiency is important. The recognition algorithm is based on Hidden-Markov-Models and optimized for fixed-point arithmetic available in low-cost embedded controllers. The system is highly reliable providing recognition rates significantly higher than the design target of 90 % for an alphabet of 10 gestures. The evaluation of the resulting solution has yielded an effectiveness of 97 % and mean execution times of less than one second. These performance figures are sufficient to consider the presented system an effective and energy efficient alternative to systems that depend on remote computation. It provides autonomous and reliable interaction for single-handed operation of mobile devices in rough industrial settings. © 2012 IADIS.

In this paper, global exponential stochastic stability based continuous gain-scheduled robust L-two-L- infinity filtering problem is studied for a class of stochastic neutral systems subject to time-varying parameters. First, the stochastic time-varying neutral systems are described by a series of stochastic time-constant systems at some selected time points, then based on stochastic Lyapunov-Krasovskii functional approach, a new globally exponentially stochastically stabilizable criterion is derived for each of the jumping system by means of linear matrix inequalities. Subsequently, L- two-L-infinity filtering systems are designed for such linear jump systems. Finally; continuous gain-scheduled approach is employed to design time-varying filter systems for the whole working region. A simulation example shows the effectiveness and potential of the developed techniques.

In order to overcome the drawbacks of the conventional nonlinearity inversion control method for block-oriented systems, a Multi-PI control method is proposed. The virtue of the proposed method is that the classic PI control algorithm is applied to complex nonlinear systems, which largely simplifies the control problems and improves control performances. Simulations demonstrate the effectiveness of the proposed Multi-PI control method for block-oriented systems with strong nonlinearity. © 2012 Springer-Verlag London Limited.

While nowadays inspection and maintenance is mainly performed manually, the deployment of mobile robot systems could reduce the necessary resources for these tasks in the future. Within this paper major hindrances and possible remedies for the deployment of teleoperated mobile robots in industrial environments are discussed. Specifically, concepts for the seamless integration of mobile robots into industrial infrastructures, for intuitive feedback and commanding of such robots as well as advanced user-interfaces are elaborated. It is discussed in how far this multi-modal approach promises to significantly improve the usability of teleoperated robots for industrial applications.

This paper is concerned with minimum error entropy filter design for non-linear Networked control Systems (NCSs) with multiple-packet transmission mechanism. Since the error of the filter in NCSs is generally non-Gaussian, the filter is designed under the information theoretic learning frame. The convergent condition of the proposed filter is established. A simulation example shows that the proposed approach is feasible and effective. Copyright © 2012 Inderscience Enterprises Ltd.

An improved included angle dividing method is proposed for Hammerstein systems. In this dividing method, nonlinearity of the system is taken into account to distribute gridding points, so distribution is more reasonable and computation load in dividing is reduced largely. Based on the dividing result, a multimodel predictive controller is designed to overcome the drawbacks of the common nonlinearity inversion control method for Hammerstein systems.

The quadrotor unmanned aerial vehicle (UAV) has been a focus for unmanned aerial vehicles. Ground control system (GCS) is an important part of the quadrotor UAV flight control system, and it can promote the flight performance and safety of quadrotor UAVs. In this paper, a quadrotor UAV GCS is designed and implemented, and the GCS realizes the following functions, including receiving and storing of the flight data, the real-time localization utilizing the customization of electronic maps like MapX and Google Earth, the visual display of flight states via virtual instruments and the waypoint planning.

第23届过程控制会议

作者： Jingjing Du Wei Qian Chunyue Song School of Electrical Engineering and Automation Henan Polytechnic University Jiaozuo 454000 State Key Lab. of Industrial Control Technology Institute of Industrial Process Control Zhejiang U

A gridding algorithm based on gap metric is proposed for multimodel control of nonlinear systems. In contrast to the common evenly distributed gridding algorithm used in multimodel decomposition, the proposed gap metric based gridding algorithm aims to reduce reliance on previous knowledge and experience and makes the gridding more systematic and more reasonable. Based on the proposed gridding algorithm, an improved integrated multimodel H∞ loop-shaping control is developed, which realizes information symmetry between local linear model selection and local controller design, and raises the efficiency of multimodel controller design largely.

In recent years, quadrotor helicopter has become a hotspot of the research about unmanned aerial vehicles (UAVs). The data acquisition of the vehicle's attitude and position in real time is important to achieve autonomous flight control for quadrotor UAVs. In this paper, an ARM embedded system is employed as the main controller, and an attitude heading reference system (AHRS) is utilized as the main onboard sensor. By using C++ programming under Linux operation system, the data acquisition and processing of the AHRS is implemented, and then the attitude and position data of the quadrotor UAV are obtained in real time to provide reliable flight state information for the autonomous flight control. The on-board flight data is sent to ground control system and stored via a communication module based on the UDP network protocol.
