In this paper a simplified frequency response computation was considered for fractional order systems with multiple linear uncertainty structures. Bode and Nyquist envelopes of systems with various multiple versions of affine, interval and single parameter uncertainties were obtained using a 2q-convex parpolygon algorithm. Results were illustrated via examples.
