Stochastically Resilient Design of Mixed H2-Dissipative Observers for Discrete-Time Nonlinear Systems
IFAC Proceedings Volumes
Original Item ID
A linear matrix inequality based mixed H2-Dissipative type state observer design approach is presented for smooth discrete time nonlinear systems with finite energy disturbances. This observer is designed to maintain H2 type estimation error performance together with either H∞ or a passivity type disturbance reduction performance in case of randomly varying perturbations in its gain. A linear matrix inequality is used at each time instant to find the time-varying gain of the observer. Simulation studies are included to explore the performance in comparison to the extended Kalman filter.
