Abstract
In this work necessary and sufficient conditions for the product, of SPR functions to be a SPRO function are given. Also, sufficient conditions are given for the composition of SPR. functions to be a SPR function. As a consequence, a result on robust strictly positive real transfer functions, under nonlinearly correlated perturbations in the coefficients, induced by the composition and product with SPR functions is presented. Based on these facts, we give an application on preservation of robust and simultaneous stabilization of SISO, LTI systems. The applicability of the results is demonstrated through two examples.
