15. Feasibility test of tracking control to moving target in dual-state trolley control system.

Author

Kim, Dongho, Park, Youngjin, and Park, Youn-sik

Abstract

In this paper, the performance of tracking control algorithm to apply to the mobile harbor(MH) crane trolley control system is verified with 1/20 scale experiment. MH is a novel maritime cargo transfer system which is recently proposed by KAIST. A relative motion between MH and container ship is caused by external disturbances such as wave and wind because loading/unloading operation of MH system is performed in open-sea condition. It is necessary to control the position of containers to the target position in this condition accurately. Using dual-stage trolley control system of MH which is proposed to control the position of trolley independently, the receding horizon controller is designed to track the moving target position. Through the 1/20 scale model experiments as the frequency of reference signal is changing, the feasibility of tracking control of MH crane system is checked. [ABSTRACT FROM PUBLISHER]

24. A study on stability of passive dynamic walking model with flat feet.

Author

Jeon, Yonggwon, Park, Youn-sik, and Park, Youngjin

Abstract

Biped robots based on limit cycle walking paradigm commonly need less energy than other models and generate pretty natural gait, since this paradigm has fewer artificial constraints on walking motion compared to other conventional ones. To increase its performance and to realize a practical biped, the model needs further studies on its stability, disturbance rejection capability, and versatility, etc. In this paper, flat feet are added to increase its stability and disturbance rejection capabilities. Although flat feet model have been already studied, their stability properties are not clarified especially in the view of bifurcation route to chaos and global stability. The stability properties of modified feet models are analyzed and its effects are compared to the results of the simplest walking model whose stability properties are already well known.
