A feed-forward control system has elements with transfer functions as
G_(d)=(5)/(6s+1),G_(p)=(3)/((3s+4)(2s+7)),G_(m)=3,G_(f)=(2)/(s+7)
Find out the transfer function of the controller and the setpoint measuring element
when the system is capable of eliminating the disturbance. Also, draw the block
diagram of the whole system with transfer functions.
