Observation and identification via HOSM-observers

Abstract

The idea of using a dynamical system to generate estimates of the system states was proposed in 1963 by Luenberger for linear systems [Lue64]. In spite of the extensive development of robust control techniques, sliding mode control (SMC) remains a key choice for handling Boundedness uncertainties/ disturbances and unmodeled dynamics in both control and estimation problems. During the last decade, SMC techniques have been widely used to design observers (sliding mode observers) suitable for robust state estimation even in the presence of unknown inputs. © 2011 Springer-Verlag Berlin Heidelberg.
