pls assist with following question

process control

3.1. What is the difference between feedback and feedforward control loops? 3.2. A system is controlled using a feedforward control system with the following transfer functions: Gc=sKc,Gsp=s+1Kc,Gd=Kc,Gf=4Kc,Gp=s+11andGm=2Kc NB: For feedforward system, the transfer function is: Y(s)=Gp(s)Gf(s)Gc(s)Gsp(s)Ysp(s)+{Gd(s)Gp(s)Gf(s)Gc(s)Gm(s)}D(s) Use OCTAVE to do the following: 3.2.1. Find the transfer function at the setpoint ( i.e. Ysp(s)Y(s)) and disturbance (i.e., D(s)Y(s)) side. 3.2.2. Find the poles and zeros and plot 3.2.3. Plot the pzmap of the transfer function
