Abstract :
An algorithm is proposed for automation of the prefilter design step of Horowitz´s quantitative feedback theory (QFT) to robust feedback system synthesis. The proposed algorithm uses interval global optimization techniques to give an ´optimal´ (to a user specified accuracy) minimum phase prefilter. The proposed algorithm is demonstrated on a QFT benchmark example
