This article presents a design method for an observer-based guaranteed cost controller for a class of uncertain linear systems, in which full state variables cannot be measured. The perturbations are assumed to be described by structural uncertainties. The linear matrix inequality (LMI) approach is applied to design the observer-based controller. The controller and observer gains are obtained by solving the LMI optimization and feasibility problems, respectively. A numerical example shows the potential of the proposed method. © 2008 International Symposium on Artificial Life and Robotics (ISAROB).

In this article, equations of motion of a manipulator, whose mechanism has a passive revolute joint, are derived in consideration of the characteristics of driving source. Considering the fi nal condition of displacement and velocity of the passive joint, trajectories of velocity for energy saving are calculated by iterative dynamic programming. And the dynamic characteristics of manipulator control based on the trajectory for energy saving are analyzed theoretically and investigated experimentally. © International Symposium on Artificial Life and Robotics (ISAROB). 2008.

For the purpose of enlarging the work space of manipulator, this study proposes the trajectories for saving energy about throwing motion. In this paper, equations of motion of a manipulator, whose mechanism has two actuated joints and a passive revolute joint for a tray, are derived in consideration of characteristics of driving source. In order to prevent the object falling from the tray, the passive joint for the tray is rotated by inertia force about actuated joints. Considering the condition about motion of the tray, trajectories for saving energy of two actuated joints are calculated by iterative dynamic programming. Initial searching region of dynamic programming is a shape which is surrounded by two cosine-wave translated in parallel. This proposed searching region is used as an initial range of the iteration method, and the region is shifted to minimize the energy consumption of the motor. The dynamic characteristics of manipulator controlled based on above mentioned trajectory are analyzed theoretically and investigated experimentally.
