State estimation is an essential component of any model-based control system. In particular, partial state estimation is favorable when the full set of the states of a system is not observable or detectable, or for large-scale systems that need only a few functions of the states to be monitored. This chapter overviews recent advancements in functional observer design algorithms for linear time-invariant systems. The concept of functional observability is explained for systems with and without perturbations, as a generalization of observability or detectability perceptions. Moreover, delay-free and delay-dependent functional observer design schemes for linear time-delay systems with state and input delays are illustrated. Since the exact delay values are often not measurable in practice, a methodology is demonstrated to deal with uncertain state delays in designing delay-dependent functional observers. In light of that, an auxiliary time-varying delay with arbitrary bounds is exploited in the observer, which effectively relaxes the conservative nature of delay-free observers.
