This is a question our experts keep getting from time to time. Now, we have got the complete detailed explanation and answer for everyone, who is interested!
Open loop control systems are those in which the output cannot be the desired output and no feedback is employed. As a result, the gain of the system is extremely high and the damping is extremely low; as a result, the system has a tendency to oscillate.
Is there a possibility that a closed loop system might oscillate?
A block diagram, such as the one displayed in the image below, can be used to provide a description of the closed-loop control system. These are the types of systems in which the control action is determined by the result of the process. These systems have a propensity to exhibit oscillatory behavior.
Which of the following systems is not prone to oscillation?
Explanation: A good control system will primarily consist of a negative feedback closed loop control system. In such a system, the gain of the system will not be too high, damping will be present, there will be no oscillations, and the output response will be quick.
Which of these is a system with a closed loop?
A closed loop control system is a collection of mechanical or electrical devices that, without the involvement of a human operator, automatically adjust a process variable to a desired state or set point…. The input of human operators is not required in closed loop control systems, in contrast to open loop control systems or switchable control loops.
What exactly is meant by the term “open-loop control system”?
The type of continuous control system known as an open-loop system, which is also known as a non-feedback system, is one in which the control action of the output signal does not have any influence or effect on the control action of the input signal. To put it another way, an open-loop control system does not involve the output being measured or “fed back” in order to make a correlation with the input.

What exactly is an example of an open-loop control system?
Open-loop control is characterized by the fact that the control action coming from the controller is not dependent on the “process output.” A boiler used for central heating that is regulated solely by a timer is a good illustration of this principle since it ensures that heat is applied for the same amount of time no matter what the current temperature in the building may be.
What exactly does it mean to have a system that is closed loop?
Examples of closed loop control systems are servo motors and any automatic motor speed controllers. A motion sensor is provided for use in this setting in order to check or monitor the speed of the motor.
Which of the systems listed below is an example of a closed loop system?
The automatic control system is another name for the closed loop system for this reason.
Is there an illustration of a closed-loop system in the Mcq?
As a result, the appropriate response is an option. 2) The example of a closed-loop system that we have here is the traffic light system. In both cases (a) and
Has a tendency to fluctuate from one point to another where: a) the system is open; b) the system is closed; c) both a and b; or d) neither A nor B?
The appropriate response is option “A.”
The difference between an open loop and a closed loop control system is as follows:
The required output in an open-loop control system does not depend on the controlled act in the same way that it does in a closed-loop control system, where the required output is primarily determined by the controlled act. This is the primary distinction between open-loop and closed-loop control systems.
Which one of the following components of an automatic control system does not contain it?
Which of the following components of an automatic control system does not make use of the said component? Explanation: Because the oscillator makes the oscillations more extreme, and since we want to make the oscillations less extreme, we do not utilize oscillators in automatic control systems. This is because the oscillator makes the oscillations more extreme.
Which of the following is NOT a disadvantage of utilizing a control system with a closed loop?
- The closed loop systems are difficult to understand and expensive to implement.
- Oscillatory response is possible in closed-loop control systems due to the presence of feedback.
- Because of the feedback, the total gain of the system is decreased.
Which of the following steps should be taken to stabilize a system that is currently unstable?
Which of the following steps should be taken to stabilize a system that is currently unstable? When a system is unstable, the gain of the system should be increased to keep it stable. When a system has positive feedback, the gain is greater; when it has negative feedback, the gain is reduced, which can cause a stable system to become unstable.
Which of the following statements about an open loop control system is not true?
Open-loop systems are imprecise in nature and also unreliable. Due to the fact that these are non-feedback systems, there is no method to automatically adjust them in the event that their output is impacted by certain external disturbances.
Which of the following is an illustration of a closed loop control system?
It is referred to as a “closed loop control system” when the control system generates output by using the feedback signal that it receives. Examples include an automatic electric iron and many types of air conditioners. By utilizing a feedback loop, closed-loop systems are able to automatically fix faults that have been generated in the output.
Mcq: Which of the following is an example of a closed loop control system?
Systems with a Closed Feedback Loop Answer to MCQ Question 8 with Full Explanation
Thus the closed-loop control systems are called automated control systems.
Is there a closed-loop system for the air conditioner?
Air conditioning, heating, and other industrial applications can all benefit from the use of closed-loop systems, which are constructed to transfer heat through flowing water. In other applications involving heating, ventilation, and air conditioning (HVAC), the water in the closed loop serves as the condenser for distant water-source heat pump installations.
Is cruise control a system that uses a closed loop?
In a control system with a closed loop, the input is modified depending on the value of the output of the system… By changing the amount of torque that the engine produces, the cruise control feature enables the driver to maintain a certain speed for the vehicle, independent of the circumstances of the road.
Is there a closed loop system in the refrigerator?
A closed-loop system would be something like a refrigerator. A thermostat is used to monitor its temperature. This thermostat will activate the motor when the temperature reaches or exceeds the predetermined threshold, and it will deactivate the motor when the temperature drops below the predetermined threshold.
Some examples of control systems include the following:
Control systems can be found in many aspects of your day-to-day life, such as an air conditioner, a refrigerator, an air conditioner, a toilet tank, an automated iron, and many of the functions found within a car, such as cruise control.
