A robust finite-time convergent hybrid observer for linear systems [PDF]

52nd IEEE Conference on Decision and Control, 2013
Motivated by the design of observers with good performance and robustness to measurement noise, the problem of estimating the state of a linear time-invariant system in finite time and with robustness to a class of measurement noise is considered. Using a hybrid systems framework, a hybrid observer producing an estimate that converges to the plant ...
