Description In this paper, an interval analysis algorithm is proposed for the automatic synthesis of fixed structure controllers in quantitative feedback theory (QFT). The proposed algorithm is tested on several examples and compared with the controller designs given in the QFT literature. Compared to the existing methods for QFT controller synthesis, the proposed algorithm yields considerable improvement in the high frequency gain of the controller in all examples, and improvements in the cutoff frequency of the controller in all but one examples. Notation : R denotes the field of real numbers; R-n is the vector space of column vectors of length n with real entries. A real closed nonempty interval is a one-dimensional box, i.e., a pair x=[x,x] consisting of two real numbers x and x with x
