ジャーナル フリーThis paper is devoted to path following control for port-Hamiltonian systems whose desired path is time-varying. Most of the existing results on path following can only take care of time invariant paths, hence they cannot be applied to control systems whose environments change, e.g., path following control with a path crossing itself or with moving obstacle avoidance. The proposed method solves this problem by employing decoupling control of three particular directions in the phase space which allows one to assign time-varying potential functions and vector fields.抄録全体を表示PDF形式でダウンロード (471K) -

ジャーナル フリーThis paper proposes a control system to keep hydrogen generation by a reaction between water and activated aluminum particles at desired level. Because the activated aluminum particles are produced shredded aluminum sawdust, the characteristics of hydrogen generation vary depending on its samples. Therefore, the fuzzy control system to determine the quantum of the activated aluminum particles is designed based on the measured characteristics of hydrogen generation. Error form a desired value, error rate and dead time of the reaction are chosen as the labels of the proposed fuzzy membership functions. The reactor vessel that the activated aluminum particles are put into is developed to generate hydrogen continuously. Three types of aluminum particles of the characteristic are used for the experiments. The proposed system is confirmed to be useful for the control of hydrogen generation, coping with the effect of reacting characteristic changes according to the activated aluminum samples.抄録全体を表示PDF形式でダウンロード (1342K)

ジャーナル フリーIn cookery science, it is already known that the application of heat contributes flavors, which improve palatability. Instruments for measuring temperature include a thermocouple. However, they cannot measure a temperature difference during cooking because of cook's motions. Therefore, we suggest a non-contact temperature measuring system by using a unit constituted by a visible and an infrared thermographic camera. In this study, we focus on the time-series temperature of a pan and of ingredients inside the pan in order to analyze quantitatively stir-fry cooking techniques.抄録全体を表示PDF形式でダウンロード (1842K)

ジャーナル フリーThis paper describes a robust navigation system using environmental magnetic field for outdoor autonomous mobile robots. In this research, a 3-axis magnetic sensor is used to scan DC magnetic field in the outdoor environment to build a database. The robot navigates by performing trajectory tracking based on the database. Furthermore, by performing data matching between sensor readings against the database at the areas where the characteristic changes of the magnetic field are detected during the navigation, the robot is able to localize with a reliable accuracy and by applying the localization results to compensate the odometry, the cumulative error can be eliminated.抄録全体を表示PDF形式でダウンロード (1972K) -

ジャーナル フリーIn this paper we propose a new type educational program for Mechatronics design which contributes to develop the physical sense and problem solving ability of the students who study Mechatronics design. For this program we provide a new handicraft kit of 4-wheeled car which is composed of inexpensive and commonplace parts, and the performance of the assembled 4-wheeled car is sensitive to its assembly arrangement. And then we implemented this program with the handicraft kit to the university freshmen, and verified its effectiveness, and report the results of the program.抄録全体を表示PDF形式でダウンロード (2927K)
