摘要：
In this paper, we show firstly that a differentially observable system affine with respect to the unknown input can be put into a triangular form. For systems under this form, we propose two strong practical observers. The first one has a constant gain while the second has a time-varying gain. (C) 2007 Elsevier B.V. All rights reserved.
