A two-degree-of-freedom design of simple adaptive servosystems is considered for a linear continuous-time plant. A reference model is introduced for specifying a desirable transient response, while an integral compensator is used in order to cope with a constant disturbance input. Then, an adaptive control law is proposed, which achieves a suitable model following control independently of selection of the integral gain. That is, a disturbance rejection property can be tuned by the gain arbitrarily without changing the adaptive control law, which is a significant feature of this simple adaptive servosystem.

The first commitment period of the Kyoto Protocols has started this year to prevent the global warming. There are many efforts and discussions on effective greenhouse gas (GHG) reduction. The emissions trading is one of important issues. Several experimental markets are starting by governments and private sectors. However, there are some opinions against the trading itself. Also, the estimation of trading amount and market price is difficult with such a huge and emerging market. In this paper, we introduce the international emissions trading with the agent-based approach and a scalable simulation framework applied to large-scale traffic flow.

In this paper, we described an abnormal condition detection system that uses a wireless wearable biosensor that can observe triaxial acceleration, ECG, and the temperature of the surface of the body. We implemented a feature that detects falls to determine a hard impact from acceleration data. Our system achieved a fall detection rate of 90.9% with a 2.8% false positive alarm rate and a 9.1% false negative alarm rate. We also implemented a feature that detects an abnormal heart rate and we determined that the feature works correctly.

In this paper, a simplified design of I-P controller for a higher-order plant by using the concept of plant model reduction mid the CRA method with less number of characteristic ratios alphai is presented. The Pade type approximation method is used to obtain a lower-order plant model of the higher-order plant first. Then an I-P controller is designed for the model by using CRA method with the appropriate values of characteristic ratios in order to obtain the closed-loop step response without overshoot. Finally, the designed I-P controller is employed to control the original higher-order plant. The sufficient performance of the speed control of a two-inertia system employing the I-P controller designed from its lower-order plant model is shown by the simulation results. The simulation results of the speed control in term of varying the value of a factor beta greater than one in the design, tracking the motor speed, and rejecting the disturbance effect are also investigated.

This study showed how hazardous scenes recorded by vehicle driving recorders are introduced to the driving lessons with the simulators. First, we investigated which trigger is useful for automatic extraction of dangerous interruption scenes from large amounts of recorded driving data. It was implicated that the relative speed to the leading car and the number of checks of the side mirror before the lane change were candidates of triggers. Secondly, an experiment was performed to examine what kind of presentation method of replayed scenes may have an effect on improving driverspsila realization of the risk in their driving through the lessons. Three perspectives in replaying the scenes were compared: a birdpsilas-eye view, a sideways view, and a looking-from-behind view. Young and elderly drivers participated in the experiment. As a result, the birdpsilas-eye image of driverpsilas own driving data lengthened the distance to the oncoming car on the right lane in lane changes for the young drivers. In contrast, the replay of their driving from the looking-from-behind perspective made the elderly drivers keep the distance to the car behind. As for presenting the replayed scenes of interruption in the driving lessons, it was suggested that the birdpsilas-eye image of driverpsilas own driving data may be most effective for inhibiting risky interruptions while the effect might be limited for the elderly drivers.

We propose a template matching method for component inspection of SMD assembly system. To discriminate wrong assembled components, input image of component is matched with its standard image by template matching algorithm. For a rapid inspection system, the calculation time of matching algorithm should be minimized. Since standard images of all components located in a PCB are stored in computer, it is desirable to minimize the memory size of standard image. We apply the discrete wavelet transformation to minimize the image size as well as the calculation time, Only 7% information of original image is used to discriminate goodness or badness of component assembly. Comparative results are presented to verify the usefulness of the proposed method.

It is dangerous that a technician inspects the inner space of an oil tanker because of many harmful gases. But inspection is necessary to many older oil tankers. In this reason, we study a design of mobile robot for inspection of CAS. The developing CAS mobile robot is able to measure an oil tankerpsilas thickness of steel plates, inspection of the inner surface, and moving the surface of a wall of the oil tanker. We focus on recognizing of corrosion state at the steel wall of ship. To improve an effectiveness of driving to move the surface of the wall of ship, magnetic omnidirectional wheels will be used. The North Starreg sensor will be used for the path planning in the oil tanker. In this paper, the experimental results showed that the robot could recognize a corrosion state of steel plate thickness of ship.

The objective of this paper is to develop a strategy system in a robot soccer system with cooperative ability which is improved by self-learning. A reinforcement learning method based on the zero-sum game theory is developed in this paper. It enforces learning systems to choose an appropriate strategy complying with the opponentpsilas actions. In order to achieve the purpose of cooperation, the system consists of two sub systems, one is a role assignment system, and the other is a reinforcement learning system.

This paper proposes a new throttle control algorithm for synchronizing the intake valve dynamics. The throttle is controlled proportionally according to the pressure in intake manifold, so that the pressure is regulated as a constant value and efficiency of air intake is improved. This control leads to the synchronization of throttle with the intake valves. A simulation result is also presented for a gasoline engine model.
