Knowing the system state is necessary to solve many control theory problems. In most practical cases, however, the physical state of the system cannot be determined by direct observation. Instead, indirect effects of the internal state are observed by way of the system outputs. In this sense, a filter is a system that estimates the values of internal systems variables that are not measured from the available outputs [86, 115]. More precisely, the aim of a filter design is that the induced operator norm of the mapping from the noise to the filter error is kept within a prescribed bound.
