Abstract :
The design and implementation of multimode systems under finite-precision restrictions are addressed. Earlier results linking minimum-sensitivity realizations for linear time-invariant systems to the balanced realizations are extended to the multimode and general time-varying systems. The main design problems are posed in a geometric framework, and the geometric theory is applied to switched systems and piecewise linear systems and to the general time-varying case. These optimal realizations are applied to obtain an optimal implementation of a simple multimode filter that allows the tracking of a target with low-complexity, small-wordlength hardware
