Which of the following statements is correct?Question 12AnswerA.Unlike the feed-forward controller, the bang-bang controller subsystem uses a model of the disturbance to cancel out the disturbance. That is why the effect of the disturbance is reduced in the presence of the feedback controller.B.Just like the feed-forward controller, the bang-bang controller subsystem does not use any model of the disturbance. That is why the disturbance is not reduced in the presence of the feedback controller.C.Just like the feed-forward controller, the bang-bang controller subsystem does not use any model of the disturbance. Despite this it reduces the effect of the disturbance when compared to the feedforward controller. This is because it uses measurements of the system output to adaptively compensate for the effect of the disturbance.D.Unlike the feed-forward controller, the bang-bang controller subsystem uses a model of the disturbance to cancel out the disturbance. It also reduces the effect of the disturbance by using measurements of the system output to adaptively compensate for the effect of the disturbance.

What is a disturbance in a control system?Question 1Select one:a.An input to the plant that does not influence the output.b.An input to the plant that influences the output.c.An input to the controller.d.None of the other answers are correct.e.An unmeasured output of the plant.

For each of the following statements determine whether it is True or False. Providedetailed analysis and rationale with appropriate drawings and/or equations.(1+4) x 4= 20(a) A system with a transfer function 𝑎𝑎𝑠𝑠+𝑏𝑏 can be stable if b < 0.(b) The system with transfer function 𝑐𝑐𝑠𝑠 2 +𝑏𝑏𝑠𝑠+𝑐𝑐 is a critically damped system, if 𝑐𝑐 = 𝑏𝑏 24 .(c) Consider the feedback system in Figure 2, if controller C is chosen to be a proportionalcontroller, then the system output can never track the reference, i.e., |e| = |Yref −Y| > 0.(d) For the feedback system in Figure 2, consider the controller C is a proportional-integralcontroller with proportional gain 𝐾𝐾𝑃𝑃 and integral gain 𝐾𝐾𝐼𝐼. If for the system a =1 andthe integral gain is chosen to be 𝐾𝐾𝐼𝐼 > (𝑏𝑏+𝐾𝐾𝑃𝑃)24 , the system will possess underdampedbehaviour
