Abstract :
On the basis of high-gain observers for perturbed state affine systems, an observer for a class of nonlinear systems satisfying a more general triangular structure is proposed. The design is based on interconnection of subobservers on the one hand, and saturation techniques on the other hand. Exponential convergence of the estimation error is shown under appropriate excitation condition
