Unformatted text preview: and actuator? Keep in mind that you body is part of the scheme. (c) Is this an example of feedback or feedforward control? How can you change the process to the other control scheme? Draw the process diagram for the other control scheme. Question 2: (70 points) Consider the liquid surge vessel discussed in class. Our job, as the engineer, is to design a controller to maintain a constant volume of liquid inside the vessel. (a) There are many ways to control this system. Purpose three unique controller configurations that could be used and address the points below for each configuration. A combination of two controller configurations is not considered unique. Use the same variables as the figure above. (i) (ii) (iii) (iv) (v) (b) Draw a process diagram of controller configuration (similar to the figure above) and the block diagram for the control scheme. State whether the controller is feedback or feedforward List the state, input, and output variables for the system Write the balance equation in terms of the variables listed above List any important concerns about implementing this control scheme Which controller configuration would you choose to use and why?...
