(12 Marks) Discuss the control system (the level controller and the temperature controllers) shown in figure (2). Specify the controlled and manipulated variable in each case. Discuss the type of the controller used in each case, that is, a simple feedback controller, a feedforward controller, a cascade controller, etc. Draw the block diagram of the temperature control loops.
