Consider a unity feedback system with open-loop transfer function: G(s) = 2 2+−2 system with open-loop transfer function. a) What is the system type? b) What is the open-loop gain? c) What is the steady state error for a step input? d) What is the steady state error for a ramp input? e) What is the steady state error for a acceleration input? f) Use Simulink to verify the results from c)-e). g) Is the open-loop transfer function stable, unstable or marginally stable? Why? How about the closed-loop?
