Observer design for a class of nonlinear systems subject to unknown inputs (2014)
Presentation / Conference Contribution

© 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...
