2. Figure 1 shows the mixing system in three constant-volume tanks. In this process three different streams are mix and diluted with water to a final desired composition of component A,x6(t). The manipulated variable to the process is the flow of the water. the major disturbances usually come from steam 2. i. Propose the feedback controller to control the composition of component A. ii. Propose the feedforward controller to replace the feedback controller in (i). iii. It is also possible to configure this process for feedforward/feedback control instead of feedback or feedforward control. Propose the feedforward/feedback control for this system. iv. Composition of component A can be control by manipulating the manipulated variable (flow of the water). However if the pressure of the water fluctuate, the composition of component A will fluctuate as well. Cascade control is a popular strategy for dealing with the control problems created by such water pressure fluctuations. Propose the cascade control to the system
