Abstract :
In this contribution the frequency domain design of reduced order H∞, filters of order n-κ is investigated for nth order discrete time systems with m measurements of which κ are undisturbed. Starting from the known time domain results, the polynomial matrices parameterizing reduced order a priori and a posteriori H∞ filters are derived. A simple example demonstrates the proposed design procedure.
