Advances of very large scale integration technologies present two challenges for routing problems: 1) the higher integration of transistors due to shrinking of featuring size and 2) the requirement for off-grid routing due to the variable-width variable-spacing design rules imposed by optimization techniques. In this paper, we present a multilayer gridless detailed routing system for deep submi...

This paper proposes a dynamic output feedback controllers for variable structure systems. It is based on the concept of output feedback controllers, introduced by Z ak and Hui (IEEE Trans. Automat. Control AC-38 (1993) 1509) and Kwan (IEEE Trans. Automat. Control AC-41 (1996) 1691) for matched uncertain variable structure systems in which the state is unavailable and no estimated state is requi...

This paper deals with the problem of simultaneous vibration suppression and robust attitude control of orbiting spacecraft with flexible appendages. Based on integral variable structure control theory, a discontinuous attitude control law is firstly derived to achieve the desired position of the spacecraft, taking explicitly into account external disturbance and nonlinearity. To reconstruct est...
