It k desired to design a feedforward control scheme in order to control the exit composition X4 of the two tank blending system shown in Fig. E . Flow rate q2 can be manipulated, while disturbance variables q5 and x5, can be measured. Assume that controlled variable X4 cannot be measured and that each process stream has the same density. Also, assume that the volume of liquid in each tank is kept constant by using an overflow line. The transmitters and control valve have negligible dynamics.(a) Using the steady-state data given below, design an ideal feedforward control law based on steady-state considerations. State any additional assumptions that you make.(b) Do you recommend that dynamic compensation be used in conjunction with this feedforward controller? Justify youranswer.
