Supervisory observer for parameter and state estimation of nonlinear systems using the DIRECT algorithm
Michelle S. Chong, Romain Postoyan, Sei Zhen Khong +1
A supervisory observer is a multiple-model architecture, which estimates the parameters and the states of nonlinear systems. It consists of a bank of state observers, where each ob…

On Eigenvalues of Laplacian Matrix for a Class of Directed Signed Graphs
Saeed Ahmadizadeh, Iman Shames, Samuel Martin +1
The eigenvalues of the Laplacian matrix for a class of directed graphs with both positive and negative weights are studied. First, a class of directed signed graphs is investigated…

On uniform asymptotic stability of time-varying parameterized discrete-time cascades
Dragan Nesic, Antonio Loria
Recently, a framework for controller design of sampled-data nonlinear systems via their approximate discrete-time models has been proposed in the literature. In this paper we devel…
