Modified nearest neighbor fuzzy classification (MNNFC) algorithm is proposed for the character of ship target high resolution range profile (HRRP). Ship length, dispersant, symmetry and central moments features are some stable features for ship HRRP and extracted accurately. Modified nearest neighbor fuzzy classification algorithm is designed for different features to contribute their predominance because the significance and stability of each feature are different. And the membership degree of each feature is modified differently. Experimental results with the actual measured data of 10 ships show that the proposed algorithm is very useful in ship target classification.

In this paper, the employment of two-dimensional run-length limited code is investigated for time-spreading wavelength-hopping optical CDMA systems. In the proposed architecture, the carrier-hopping prime code is utilized as signature sequences, and it is a symmetric code whose out of phase autocorrelation is zero and the cross-correlation is at most one. Based on the zero autocorrelation sidelobes property, we can apply the two-dimensional ternary symbols to the trellis run-length limited code. To further enhance the free distance of the proposed trellis code, a coset representative is added to the codeword. The multiple access interference and beat noise are the most detrimental factors of system impairment. Apart from the multiple access interference and beat noise, some of the deteriorating impacts of system performance are also taken into consideration, which include thermal noise, shot noise, and relative intensity noise.

This paper presents high voltage generator for stun gun applications. The proposed high voltage generator consists of coupled-inductor boost and flyback converters, which adopts active clamp circuit to recover energy trapped in leakage inductances of coupled inductor and transformer in two converters simultaneously. With this approach, coupled-inductor boost converter can boost voltage of battery up to a high output voltage, while flyback converter is adopted to step up the output voltage up to the desired voltage of capacitated paralysis for convicts conferring. In order to increase safety of the stun gun, transformer of flyback with a high turns ratio is used by multi-winding method in secondary winding to speed up output response and to reduce charges supplied by stun gun for meeting maximum enduring charges of human body. Since switches in the proposed generator adopts switch integration technique, its weight and volume can be reduced and its conversion efficiency can be increased. As compared with conventional stun gun, the proposed one can achieve 210 ten-second firings which exceeds 1.5 times of ten-second firings of the conventional one. Finally, a prototype under maximum output voltage of 30kV and maximum output current of 5mA has been implemented to verify feasibility of the proposed high voltage generator.

Climbing capability, as an important index to assess the performance of the power transmission line (PTL) inspection robot, directly concerns the robot practical application. In the former design, in order to enhance the climbing capability, the common method is to choose a drive motor with high torque and a transmission system with large reduction ratio. However, as a matter of fact, climbing capability of the inspection robots using the method mentioned above does not become very satisfied. This article analyzes the influence of posture and drive wheel on the climbing capacity, proposes a new method to improve climbing capability by changing the robot posture during climbing and optimum design for drive wheels, which could enhance the adhesion capability and balance the load, and finally validates the correctness of the proposed method by simulation and experiments. The research contents are also meaningful to some other mobile robots.

This article addresses the multiple cameras — multiple target points visual servoing system to correct the pose of robot end-effector in large scale manufacturing systems. The end-effector of a 6 Degree-of-Freedom (DOF) robot holds the workpiece and four cameras are used as visual sensors and installed on the workpiece to capture the image features of target points. Four pairs of light emitted diodes (LEDs) are installed above the workpiece configured in a way that, each pair LED can be observed by only one camera. One pair LED contains one target point for visual servoing and one complimentary point for estimating the depth of the corresponding target point to relevant camera. In this configuration, the depth of each target point to the corresponding camera is readily obtained by using the stereo vision method. Hence, the image Jacobian matrices can be precisely calculated during visual servoing. An imaged based visual servoing (IBVS) controller is designed to control the pose of the end-effector of robot and hence that of the work piece. By observing the four target points, the IBVS can drive the workpiece to the desired position in robot base frame. Extensive simulation has been carried out to verify the effectiveness of the proposed method.

This paper presents a novel isolated buck converter with output voltage ripple reduction by a complementary square-wave scheme. The converter is composed of a forward DC-DC converter, a half-bridge inverter, and a common LC filter. The outputs of forward converter and halfbridge inverter are connected in series, so that their square-wave outputs are added to form one constant DC voltage. The LC filter is used to remove the output ripples, which are induced by light loading, and noise of the DC voltage so as to obtain a steady output voltage. The circuit can also lower the switching frequency, and decrease the circuit transient response effect of one LC filter. So it is one easily controllable isolated DC-DC buck converter with high stability and low cost. Simulation results have been provided confirm the proposed method. Experiment will also be done soon to verify the performance.

The major obstacles to teaching Programmable Logic Controller (PLC) is a variety of PLCs and the rapid pace of technological development with new models and innovations. Moreover, costs incurred in the setting up of comprehensive and modern PLC laboratory facilities, and in the required periodic updating of teaching material and equipment are, as a result, very high. After investigated the conception and features of PLC and embedded system, the development of the embedded PLC for teaching machatronics students is proposed in this paper with the seamless combination of the LabVIEW software and the ARM Microcontroller with the LabVIEW embedded module. The flexibility of the proposed PLC makes it relatively easy and less costly to teach the basic principle of different kinds of PLCs due to their variety and rapid change. The implementation of the embedded PLC is discussed and evaluated. The results of evaluation shows that embedded PLC can be taught in an uncomplicated manner.
