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

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 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 the following is are the advantages of a closed loop control system?

Advantages of closed loop control systems: The closed loop systems are accurate. The closed loop systems are accurate even in the presence of non linearities. The sensitivity of the system may be made small to make the system more stable.

Which among the following represents an illustration of close loop system?

Explanation: Closed loop control system is the system with the positive or negative feedback and this is made so as to avoid the disadvantages of open loop control system and in the above options automatic washing machine represents closed loop system.

Which of the following elements are used in an automatic control system?

Q. In an automatic control system which of the following elements is not used ?
B. final control element
C. sensor
D. oscillator
Answer» d. oscillator

Which element is used in an automatic control system?

Feedback controls are widely used in modern automated systems. A feedback control system consists of five basic components: (1) input, (2) process being controlled, (3) output, (4) sensing elements, and (5) controller and actuating devices.

Which of the following is used to determine controllability of the system?

Explanation: Kalman’s test is the test that is done for the controllability and observability by solving the matrix by kalman’s matrix individually for both tests.

How do you determine a good control system?

Elements of a good Control System

  1. 1) Feedback.
  2. 2) Control must be objective.
  3. 3) Prompt reporting of deviations.
  4. 4) Control should be forward-looking.
  5. 5) Flexible controls.
  6. 6) Hierarchical suitability.
  7. 7) Economical control.
  8. 8) Strategic control points.

What is a control system what are the key features of a good control system?

A good control system must be responsibility- based, in its operation. It must pinpoint responsibility on personnel or departments; who/which are responsible for the occurrence of deviations- so that necessary corrective steps are directly focused at them – without involving innocent elements.

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.

What is open and closed loop control system?

An open-loop control system (also known as a non-feedback system) acts completely on the basis of input; the output has no effect on the control action. A closed-loop control system looks at the current output and alters it to the desired condition; also known as a feedback system.

What is closed loop control?

A closed loop control system is a mechanical or electronic device that automatically regulates a system to maintain a desired state or set point without human interaction. It uses a feedback system or sensor.

What is control system Mcq?

Explanation: Control System is a system in which the output is controlled by varying the input.

Which of the following is are the continuous control modes used in control system?

The control actions most commonly used in process control are one or a combination of the continuous process controller mode. In these modes, the output of the controller changes smoothly in response to an error or error change rate.

Which of the following is an open-loop 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.

Which of the following elements of a control system detects change?

Sensor, or sensory receptor, is the cell, tissue, or organ that senses the change in the stimulus or physiological variable.

What are the types of automatic controls?

Automatic control systems can be classified into four main types:

  • Two-position controllers (ON/OFF).
  • Proportional controllers.
  • Integral controllers.

Which of the following is element of control?

Q. The following is (are) the element(s) of control
B. Guidance and direction
C. Constraint and restraint
D. All of the above
Answer» a. Authority and knowledge
