Effective training is essential for human teleoperators to deliver satisfactory performance in actual tasks. Teleoperation is naturally a very difficult task due to the absence of naked-eye vision that cripples the cognitive behavior of the remote operator. Camera vision somehow is not a satisfactory substitution. However, training with naked-eye vision feedback may help human teleoperators to learn how to deliver satisfactory performance when they actually interact with camera vision. This study was carried out to further investigate this hypothesis, and to quantitatively supplement it with experimental proofs. For this cause, the recently built telerobotic test-bed between KAIST (Korea) and Saga University(Japan) was reshaped to a telerobotic mini-golf system, which is the trial experiment in this study. The performance of the players with and without naked-eye training was compared and quantitatively evaluated. The effectiveness of training with naked-eye vision was verified as an essential part in training human teleoperators.

A four-leg pulse width modulation (PWM) voltage source converter (VSC) is used to supply three phase balanced voltage even under an unbalanced load condition in three phase four wire power distribution network. A novel carrier-based modulation technique for the converter is described with the concept of an offset voltage and also is extended to so called 'discontinuous PWM (DPWM)' to minimize switching losses of VSC. As a practical application example of the four-leg VSC, a line interactive uninterruptible power supply (UPS) system is chosen. The feasibility of the proposed PWM strategies and control algorithms has been verified by the simulation and experimental results.

In this paper, CMIA (cell mediated immune algorithm) controller was proposed to drive the autonomous guided vehicle (AGV) more effectively. The proposed controller was based on specific immune response of the biological immune system which is the cell mediated immunity. To verify the performance of the proposed CMIA controller, some experiments for the control of steering of that AGV are performed. The tracking error of the AGV was mainly investigated for this purpose. As a result, the capability of realization and reliability were proved by comparing the response characteristics of the proposed CMIA controllers with those of the conventional PID and NNPID (neural network PID) controller.

This work proposes a novel topology and control algorithm for a three-phase line-interactive UPS system with active power-line conditioning capability. This paper presents a simple and systematic control algorithm to regulate the source current and the load voltage of the proposed UPS system using PQR transformation. A parallel inverter operating as a controlled voltage source regulates the source current sinusoidal by controlling the applied voltage on an AC line inductor. The series inverter operating as a dynamic voltage restorer (DVR) compensates for the main source voltage and rides through the output load voltage to be balanced and harmonic-free. Both of the series and parallel inverters always act as controllable voltage sources independently, so that the three-phase output voltages can transfer seamlessly between normal mode and backup mode. The proposed UPS system has high operation efficiency and high usage of the converter capacity, and good endurance against voltage transients or EMI noise resulted from the mains. The feasibility of the proposed UPS system has been investigated and verified through computer simulations and experiments by a 60 kVA prototype UPS.

The design of robust adaptive tracking control for MIMO unknown nonlinear systems, which is the combination of the approximation method of Chebyshev polynomial based unified model (CPBUM) neural network, adaptive control algorithm and H/sup /spl infin// control technique, have been successfully proposed. The proposed robust adaptive tracking control structure uses the good approximation ability, fast learning speed, and systematic design method of CPBUM neural network in controller with rough tuning and the H/sup /spl infin// disturbance attenuation technique in fine tuning. Hence, this proposed structure has good adaptability and robustness for the close-loop system. Finally, a two-degree of freedom robotic manipulator is given to demonstrate the validity of proposed method.

In this paper, we proposed an adaptive control method which is named CMIA mediated immune algorithm) controller to control unmanned container transport using in the harbor. It is based on specific immune response of the biological immune system which is the cell-mediated immune response. It is also applied for the autonomous guided vehicle (AGV) system which is manufactured in this paper. The AGV is used for the port automation to carry container manlessly and get uncertainty and nonlinearity because of running in the outdoor. To verify performance of the proposed CMIA controller, some experiments for the control of steering of that AGV are performed. Finally, the experimental results for the control of steering and speed of AGV system illustrate the effectiveness of the proposed control scheme. These results for the proposed method also show that it has better performance than other conventional controller design methods.

In this paper a novel three-phase line-interactive UPS system with parallel-series active power-line conditioning capability using AC line reactor and two four-leg voltage source converter (VSC) is proposed. The four-leg VSC can use the DC-link voltage effectively by the 3-D SVPWM method. Hence the DC battery voltage can be reduced by 15% in comparison to that of the conventional line-interactive UPS system. The parallel inverter operating as a shunt active filter is a controlled voltage source and controls the three-phase line voltage independently in order to control the source current. It eliminates the neutral line current and the active ripple power of the source side using the dqo transformation so that unity power factor and the sinusoidal source current can be achieved even though both the source and the load voltages have zero sequence components. The series inverter operating as dynamic voltage restorer (DVR) compensates the load voltage and allows it to be balanced and harmonic-free. Both of the series and shunt inverters always act as independently controllable voltage sources, so that the three-phase output voltage can show a seamless transition to the backup mode. The feasibility of the proposed UPS system has been investigated and verified through experimental results.

In the process of GAC adsorption under the conditions of 20 min HRT and 6 m/h filtration rate the removal efficiencies of UV_(254) and trichloromethane could reach 40% and 50% respectively and the UV_(254) and trichloromethane in system effluent was less than 0.015 cm~(-1) and 5μg/L respectively. In the post MF membrane process MF membrane effectively retained the particles and bacteria in raw water. The effluent turbidity was less than 0.2 NTU and no bacteria were detected at all in permeate. A computer-controlled system was employed to control this system. The membrane operating parameters of backwash interval duration and flux were studied. The backwash interval of 10-min 20-min and 60-min was researched respectively and the variation of trans-membrane pressure was also analyzed. Consequently short backwash interval was recommended under the same water consume.

In order to support multimedia communication, it is necessary to develop routing algorithms that make decisions based on multiple Quality of Service (QoS) parameters. This is because new services such as video on demand and remote meeting systems have multiple QoS requirements. However, the problem of QoS routing is difficult because finding a feasible route with two independent path constraints is NP-complete problem. Also, QoS routing algorithms for broadband networks must be adaptive, flexible, and intelligent for efficient network management. In this paper, we propose a multi-purpose optimization method for QoS routing based on Genetic Algorithm (GA). The simulation results show that the proposed method has a good performance and therefore is a promising method for QoS routing.

This paper introduces an effective modification for the catalyst regeneration system used to improve the octane number of the complex naphtha reformers in the refiners. Thinking for modification is initiated due to the serious problems that may happen as a result of uncontrolled temperature rise over the permissible limits in the regeneration tower (problems have been actually happened in some companies). Modification methodology depends on an addition of a new temperature element into the most effective area of the regeneration tower, and then a fuzzy control module is built in the existing distributed control system (DCS) to automatically control the system behavior. This approach will enhance system performance and improve factor of safety over the supplier regulation, which mainly depends on the human behavior, and tracing the temperature before the critical area. Through this paper, the catalyst regeneration process is described, the temperature rise problem is classified and several solutions to prevent such problem are proposed. Simulated results are presented to show system response with the proposed modification and to validate such solution for practical implementation.
