This paper is concerned with obtaining necessary and sufficient conditions for fulfilling specified state and control pointwise-in-time constraints against a certain class of nonlinear dynamics. The results are generalizations of the maximal output admissible set theory to the case of nonlinear systems. Main contribution of the present paper is that(More)
The model-based approaches for tracking of human bodies in image sequences can be categorized into two types; tting model to body frame by frame, and accumulating estimated pose displacements in successive frames after model tting at the initial frame. The latter has an inherent drawback as accumulation of tracking errors while the one has a great advantage(More)
This paper proposes a new subspace identification algorithm for continuous-time systems using generalized orthonormal basis functions. It is shown that a generalized orthonormal basis induces the transformation of continuoustime stochastic systems into discrete-time stochastic systems, and that the transformed noises have the ergodicity properties.
