© 2015 Institute of Control, Robotics and Systems - ICROS. This paper deals with the problem of observer-based controller design for a class of nonlinear systems subject to unknown inputs. A novel method is presented to design a controller using esti... Read More about Observer-based control design for a class of nonlinear systems subject to unknown inputs: LMI approach.

© 2015 Elsevier Ltd. We consider a novel method to design H∞ observers for a class of uncertain nonlinear systems subject to unknown inputs. First, the main system dynamics are rewritten as an augmented system with state vector including both the sta...

Copyright © 2014 John Wiley & Sons, Ltd. We present a robust H∞ observer for a class of nonlinear discrete-time systems. The class under study includes an unknown time-varying delay limited by upper and lower bounds, as well as time-varying paramet...

© 2014 EUCA. We consider a novel method to design an observer for a class of nonlinear discrete-time systems with unknown inputs. Based on Lyapunov functional, we derive a sufficient condition for existence of the designed observer which requires sol...
