Özet

The paper presents a method for computation of the Nyquist envelope of fractional order interval control systems (FOICS). The given method is based on the computation of the value sets of fractional order interval polynomials (FOIP). The results obtained will be useful for estimating the frequency domain specifications such as robust gain and phase margins, and for designing robust controller for FOICS.
