ut, zxpianeta Block diagram is a convenient way to represent a process, so that a control system can be constructed. The control system representation can be used to study and analyse 12 responses of process, its stability and suggest control strategies. Let say if you have a process and a model for the process has been specified as, +t+60-0.5t 12(s + 2) 4+60-0.5t Gp (s2 +9) s +3 = There are many other components to complete the block diagram control system. [a] Create any mathematical models for all blocks to represent a complete system. (Hint: What are the equipment or instrumentation involved?) [6 marks] t [b] Draw a complete closed loop blocks of the process. [2 marks] [c] Plot a process response curve for an open loop transfer function with an input. Select your own input. Use a graph paper. Ty Tb-o [6 marks] Kc Can there be any possible new model derived? How should you do? [6 marks] [d] [e] Propose a type of controller and its tuning parameters. 16 marks
