A Generalized Cubic Observer for State Estimation of Linear Systems (1912.08651v1)

Abstract: This paper extends the application of a recently proposed nonlinear observer (cubic observer) for state estimation of linear systems with unknown inputs and delays. The generalized structure proposed here, makes it possible to establish a performance advantage over a similar linear observer. Convergence criteria, performance advantages, unknown input cubic observer and observer design for delayed linear systems are discussed. A simulation example are given as well.
