STRUCTURE QUESTIONS FOR CHAPTER 2







            1.       Draw a block diagram of the open-loop system

                    and describe how the system works.



                    ANSWER











           Reference                                                                              Actual
           Input                  Controller                        Process                       Output












                 For open-loop system, the controlled output has no effect on the

                 reference input or set point, the system cannot compensate for

                 disturbance. So the output is not measured and no feedback is provided.
