Set-Membership Filter (SMF) has been extensively studied for state estimation in the presence of bounded noises with unknown statistics. Since it was first introduced 1960s, studies on SMF have used set-based description as its mathematical framework. One important issue that overlooked is optimality SMF. In this work, we put forward a new framework using concepts uncertain variables. We establ...

This paper is concerned with the heading tracking control problem for a network-based unmanned surface vessel (USV) under wave-induced disturbances. Considering characteristics of disturbances, unknown-but-bounded (UBB) noise model adopted. Meanwhile, signal quantization taken into account due to limited capacity communication channel. Based on these considerations, novel set-membership based s...

Accurate length estimation is very helpful for the successful segmentation and recognition of connected digit strings, in particular, for an oo-line recognition system. However, little work has been done in this area due to the diiculties involved. In this paper, a length estimation approach is presented as a part of an automatic oo-line digit recognition system. The kernel of our approach is a...

Accurate length estimation is very helpful for the successful segmentation and recognition of connected digit strings, in particular, for an off-line recognition system. However, little work has been done in this area due to the difficulties involved. A length estimation approach is presented as a part of our automatic off-line digit recognition system. The kernel of our approach is a neural ne...
