Optimal control of elastic structure systems taking account of spillover. (Application to a position control of elastic rotating arm).
A digital controller for an elastic structure system suffers from spillover of residual modes. In this study, this problem is formulated as a control structure constraint for the elastic system. AExpand

GROUND SETTLEMENT ACCOMPANYING CONSTRUCTION OF LARGE CROSS-SECTION SHIELD TUNNELS IN TOKYO
The tunnel construction by the shield method shows the smaller values of ground settlement than other tunneling methods. In urban tunnels, however, the displacement of the surrounding ground isExpand
