Assume control systems are in place to provide the requirements of given Problem. Now, suppose the output-control valve suddenly sticks in the closed state. Explain why the tank will not overflow.
Problem
Figure shows a manufacturing process diagram. In this process, the following independent control requirements must be satisfied:
a. Control the level at Lsp.
b. Control the temperature at Tsp.
c. Control the output flow rate at Qsp. Complete the diagram showing the control loops by using the block diagram error-detector symbols and controller blocks. Include blocks for necessary signal converters.
