In this chapter different approaches are provided to estimate the state of some classes of strongly observable linear systems with some parametric uncertainties and unknown inputs. A family of homogeneous observersHomogeneous observers and a fixed-time sliding-mode observerFixed-time sliding-mode observer are introduced to solve this problem. The finite-time and fixed-time convergence properties and the synthesis of these observers are described along this chapter. Moreover, an unknown input identificationUnknown input identification approach is also introduced. Simulation results illustrate the performance of these state estimation approaches.
