  • A position control system using hydraulic cylinder is modeled as a nonlinear system. In order to control this nonlinear system, in this paper, the fuzzy PID control technique which has time-varying control parameters is adopted. In this study, an exclusive sensor to detect the position of hydraulic cylinder is used, which is embeded in hydraulic cylinder.

  • In this paper , the basic strategic method to induce the entrants and to raise the morale of students for the maritime college has been discussed, and it is pointed out that the values of higher maritime education in the developed society have a tendency to be highly evaluated from the point of not only maintaining the national shipping but also controlling the quality of the shipping industries and marine environment. Consequently, the new maritime educational program has to be developed so that the student may make a decision to choose hir course for the future job on the base of traditional maritime training.
