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.

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.

Consider the following control problems:A) Maintaining constant DC motor speed despite a load torque being applied to the shaft. B) Maintaining an aircraft at a constant altitude in the presence of turbulence.C) Maintaining the temperature in a room at a constant level despite the opening and closing of doors.Which of these are examples of regulation problems in the presence of disturbances?Question 1Select one:A and B only.All of A, B and C.C only.A and C only.

In a typical closed loop system, the element that realizes the control input calculated by the controller and applies it to the plant is called as the plant controller actuator sensor

input control output feedback is information from one step of a cycle that affects a previous step of the cycle.

is information which indicates that the system is deviating from its planned or prescribed course and that some re-adjustment is necessary to bring it back on to course.Question 3Answera.Negative feedbackb.Positive feedbackc.Control systemd.Both positive and negative feedback
