Which of the following systems is not necessarily correct for open control system?

Which of the following systems is not necessarily correct for open control system?

Which of the following statements is not necessarily correct for open control system ?

1) Presence of non-linearities causes malfunctioning
2) Input command is the sole factor responsible for providing the control action
3) Generally free from problems of non-linearities
4) Less expensive
5) NULL

Which of the following is an open control system?

Which of the following is an open loop control system ? Explanation: In field control D.C. motor, the input is dependent of the output. So it is an open loop control system.

What is open loop control system with example?

The Open-loop Control System It is a one-way system that has no feedback to alter the machine’s operation. An example of this type of system is a timer-based toaster. Bread is put into the toaster, a timer is set, and a lever is pushed down acting as a switch to start the process.

What is the control action in open loop system?

One type of control system in which the output has no influence or effect on the control action of the input signal is called an Open-loop system. Hence in open-loop control system, the control action is independent of the desired output.

Which of the following is not a characteristics of open loop control system *?

Q. Which of the following are the not characteristics of the closed loop systems?
C. it does not involve output measurements
D. it does not has the ability to control the system transient response
Answer» d. it does not has the ability to control the system transient response

Which of the following is not a feature of a good control system?

1. Which of the following is not the feature of modern control system? Explanation: For a good control system the speed of response and stability must be high and for the slow and sluggish response is not used and undesirable.

Which of these statements are true for the open-loop system?

The answer is Option 4. An open loop control system is a system for which the control action is not dependent on the system’s output.

Which of the following elements is an open-loop system?

In a tension control open-loop system there are three primary elements: the controller, the torque device (brake, clutch, or drive), and the feedback sensor.

Which of the following are the examples of open loop control system Mcq?

Which of the following is an open loop control system?

  • Field controlled D.C. motor.
  • Ward Leonard control.
  • Metadyne.
  • Stroboscope.

What are the characteristics of open control systems?

A characteristic of the open-loop controller is that it does not use feedback to determine if its output has achieved the desired goal of the input. This means that the system does not observe the output of the processes that it is controlling.

Which one of the following is an example of open-loop system?

Correct Option: A A windscreen is an example of open-loop system.

Which of the following is disadvantage of open-loop system?

The disadvantages of open loop system are: The bandwidth of open loop control system is less. The non-feedback system doesn’t facilitate the process of automation. Open loop systems are inaccurate in nature and also unreliable.

Which one of the following is open-loop Mcq?

Which of the following is an open loop control system ? Clarification: In field control D.C. motor, the input is dependent of the output. So it is an open loop control system. 6.

Which elements and signals of a control system do not exist in an open-loop configuration?

Cards

Term An open loop-system is not self-correcting. Definition TRUE
Term Which elements and signals of a control system do not exist in an open-loop configuration? a. comparator. d. Feed-back signal b. error signal. e. All of the above. c. Measurement device. Definition e. All of the above

Which of the following is are the disadvantages of an open loop control system Mcq?

Disadvantages of open loop systems: Open loop systems are inaccurate and unreliable. The changes in the output due to external disturbances are not corrected automatically.

Which of the following elements is not used in an automatic control system?

In an automatic control system which of the following elements is not used? Explanation: In an automatic control system oscillator is not used because the oscillator increases the oscillations but our aim is to reduce the oscillations and hence oscillator is not used.

Which of the statement is correct with regard to the bandwidth of the control loop system?

D. Explanation: bandwidth is the frequency measured at the gain of 3db and for the good control system the value of the bandwidth must be large but the large value of the bandwidth increses the noise in the system.
