In this paper, a nonsingular terminal sliding mode concept is introduced for the control of a class of nonlinear dynamical systems. This nonsingular terminal sliding mode control not only enables the £nite time convergence of the system equilibrium, but also eliminates the singularity problem associated with conventional terminal sliding mode control. Simulations are presented to show the effectiveness of the design.

This paper proposes the MACE - a multi-agent based distributed measurement architecture in CORBA environment used to develop intelligent distributed measurement system for remote control and monitoring of instruments over a network such as the Internet and Ethernet. The architecture is characterized by interoperability, collaboration and intelligence by means of CORBA and multi-agent technologies. The paper describes the architecture and exemplifies it by a common project.

Firstly, this paper describes the structure, measuring theory and characteristics of a new kind of coordinate measuring machine (CMM) using parallel-link mechanism with three spatial degrees of freedom (3-DOF). Then, the measuring model of it is established according to the theory of spatial mechanics, and the workspace of the probe is calculated and verified by computer simulation. Finally, the virtual prototype of the new CMM is studied by using the graphics functions in OpenGL graphics library based on Windows 98 and Visual C++ 6.0. This research lays the foundation for manufacturing the real prototype of the parallel-link CMM.

This paper proposes a circuit configuration for the realization of a four-terminal floating nullor (FTFN) with electronically tunable current gain. It mainly consists of an op amp in input together with two complementary current mirrors with controlled gain and two standard improved Wilson (1990) current mirrors. The validity of the performance of the scheme is verified through PSPICE simulation results. Some example applications in the design of the proposed tunable FTFN as a tunable active element show that the circuit properties can he varied by electronic means are also included.

This paper is concerned with the argument that the identification of Takagi Sugeno (T-S) fuzzy models from training data should involve an important feature between data fitness and model complexity. One hand a (T-S) fuzzy model with a large number of fuzzy rules may encounter the risk of having an approximation capable of fitting training data well. On the other hand it may be difficult to run this fuzzy model structure due to heavy computational cost. In order to facilitate the development of a balance between these requirements, a Higher Order Singular Value Decomposition (HOSVD) based T-S fuzzy model reduction is introduced using the well-known Yam SVD fuzzy rule-based approximation technique.

This paper presents a novel watermarking technique for digital audio signals. A visually recognizable binary image served as a watermark is embedded into an audio signal in discrete cosine transform domain. In order to enhance robustness and make good use of masking characteristics of the audio signal, the techniques of pseudo-random permutation and energy-based permutation are used during watermarking. The experimental results show that the proposed watermarking technique is robust to several signal manipulations, such as filtering, compression, and so on.

An industrial boiler process has complicated characteristics, such as time-varying property, large delay, nonlinearity and multiple-variables coupling. For its control, a multiple control algorithm of fuzzy-PID control strategy with Smith compensator and an intelligent weight function is presented in this paper. Simulation and running results show that this algorithm has good performance, small overshoot and can reduce the static error effectively.
