Abstract :
Fitting a stable, minimum phase transfer function to magnitude date is one of the problematic points when using D-K iterations for reducing the conservatism of an H∞ design. In this paper, a new algorithm for computing a solution to this problem is presented. The algorithm is based on well known signal processing techniques and is efficient and straightforward to implement
