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.
