Consider the stable closed-loop system shown in the figure. The asymptotic Bode magnitude plot of G(s) has a constant slope of -20 dB/decade at least till 100 rad/sec with the gain crossover frequency being 10 rad/sec. The asymptotic Bode phase plot remains constant at -90° at least till ω=10 rad/sec. The steady-state error of the closed-loop system for a unit ramp input is _______. (rounded off to 2 decimal places)
