Question: The overall transfer function of a process is given by G=G1G2 where G1=1s+1K1 and G2=2s+1K21=5,2=3 (a) What is the overall gain of G ? (b)

 The overall transfer function of a process is given by G=G1G2

The overall transfer function of a process is given by G=G1G2 where G1=1s+1K1 and G2=2s+1K21=5,2=3 (a) What is the overall gain of G ? (b) For a first-order system, the time constant is the time for a step change M when y reaches 63.2% of the steady state. Is the equivalent time constant for the step response of the second-order system G (time when the response reaches 63.2% of the steady state) equal to 1+2 ? Show supporting calculations for the step response formula, y(t)=KM(1121et/12et/2) (c) Can y(t) show oscillations for a step input? Explain
