The method of designing a path-tracking robot, which can stably run on an arbitrary raceway with its speed maximized, is presented. A CCD camera is used to acquire the guide line information, so image processing is required. A predictive position find and lens distortion correction(PFDC) algorithm is proposed. Two associated problems---path optimizing and speed control problems, are considered for...
This paper discusses the design and implementation of an extremely reliable system to remotely monitor and control the subsea blowout preventer (BOP) stack by using triple modular redundancy technique. The system hardware architecture including surface component and subsea component are proposed. The control logics, human machine interface (HMI) graphical design and redundant databases are development...

At the same time, it put forward the hardware structure of the system and software...
In order to improve the underwater vehicle positioning precision, a new underwater nonlinear information fusion algorithm based on hydrodynamic model and unscented Kalman filter was proposed. Hydrodynamic dead reckoning model represented sailing nonlinearity preferably, and the algorithm using unscented Kalman filter avoided linearization error. To confirm the position estimate capability of the nonlinear...

By making full use of a single chip's ability to calculate and control, the instantaneous flux and the accumulative flux can be displayed instantly on LED display using serial data transfer. In addition, the parameters of the flow meter can be set to accommodate pipes with different calibers to improve precision...
In order to improve the load characteristics of stepper motor, give full play to the potential performance of a stepper motor, achieve higher performance, a stepper controlling system has been developed. High-speed microcontroller-based controller, enhanced parallel port (EPP) as a communication interface, Field Programmable Gates Array (FPGA) to achieve pulse signal generator, use of PC rich resources,...
This paper is composed of two sections. The job of the people such as Z. Cai. and R. Lazarov was introduced in the first section, their idea is to use first order system least squares for solving second order partial differential equations. The simplest case of first order elliptic system is Cauchy-Riemann equation, so the difference schemes of Cauchy-Riemann equation was studied in the second section.
This paper describes a new framework of laser triangulation method for measuring the distance according to the basic principles of traditional laser triangulation method, which spread the range of the traditional measuring method. This method measure the distance for particle subsection by using three independent CCD that distribute uniformly along the optical axis and detect by using the plain reflected...
Active power filter is an effective device to clear harmonics. Accurate detection of compensated components decides its compensation effect directly. This paper proposes an advanced instantaneous detection method for distorted three-phase system voltage by detecting fundamental positive sequence voltage and current respectively using d-q transformation. Thus fundamental positive-sequence active current...
This paper presents design principles of a low-power and portable bioelectrical impedance analyzer. Based on the low-power and portable notion, It uses a low-power computer as the core, adopting MSP430F149 chip as the processor and utilizing AD5933 which is launched by Analog Devices and is highly integrated to measure and collect the multi-frequency impedance information. And then these data will...
A global sliding mode variable structure controller based on fuzzy logic is adopted to Permanent magnet Synchronous Motor. First,. the controller can ensure sliding behavior throughout an entire response, we can specify the demands on the capability of the system to achieve a desired performance. Moreover, the control law is based on equivalent control, in which the function sign(·)is substituted...
The study on NOx Storage Performance at low temperature over Pt/BaO/Al2O3 by plasma treatment in this paper, the structure and activity of catalysts are characterized and tested respectively by using BET, TPR, SEM, TPD,XRD and FTIR. The results of FTIR spectra are shown that catalyst by non-plasma treatment has weak oxidbillity for NO, on the surface of catalyst, there are major adsorption species...
