ABSTRACT

A new, computationally efficient approach for automation of the prefilter design step of Horowitz’s quantitative feedback theory (QFT) to robust feedback system synthesis is proposed. In the proposed approach, we pose the prefilter design problem as an interval constraint satisfaction problem (ICSP) and solve it using well-established interval constraint satisfaction techniques (ICST). To validate the above design approach we apply this to a benchmark problem to obtain simple, low order prefilters in quick time.
