DCRAC are comparable to some extent, the transient response of AN-
RISE is better than that of DCRAC. This is reasonable because ANRISE
includes a PPF to guarantee the prescribed error bound. Nevertheless,
the transient and steady-state error of the proposed ANRISE is smaller
than ANDSC due to the use of a robust term to enhance the robustness.
