Abstract

The dual problem of robust gain and phase margins for interval systems given in transfer function form is solved in this paper. Through the introduction of “virtual compensator” in the forward loop, the problem is converted to that of robust stability of real and complex interval polynomials. Robust stability of these polynomials is tested using Kharitonov theorem or equivalently, the interlacing frequency bands criterion
