Feed forward and Feedback Control Theory Quiz

What is an open-loop control system?

• A control system that is completely automated and requires no human intervention

• A control system that relies on feedback from the output

• A control system where the output has no effect on the control action.

• A control system that only operates during specific hours of the day

Explain the concept of a sensor in an open-loop control system.

• A sensor in an open-loop control system is used to adjust the output based on the input

• A sensor in an open-loop control system is not necessary for the system to function

• A sensor in an open-loop control system provides feedback to the controller

• A sensor in an open-loop control system is not used to provide feedback to the controller.

What are the advantages of an open-loop control system?

• Simple, cost-effective, and high bandwidth

• Complex, expensive, and low bandwidth

• Difficult, inefficient, and slow

• Complicated, affordable, and limited bandwidth

Discuss the limitations of an open-loop control system.

• Unlimited accuracy and reliability

• No impact on system performance

• High cost and complexity

• Limited accuracy and reliability

Provide an example of an open-loop control system in real life.

• Refrigerator with a temperature control

• Thermostat for a heating system

• Washing machine with a timer setting

• Car with cruise control

What is a closed-loop control system?

• A closed-loop control system is a type of control system that only operates in one direction

• A closed-loop control system is a type of control system that does not involve any feedback

• A closed-loop control system is a type of control system that has no effect on the input

• A closed-loop control system is a type of control system where the output has an effect on the input, creating a loop of control.

Explain the role of a feedback loop in a closed-loop control system.

• The feedback loop only operates at the beginning of the control process

• The feedback loop has no role in a closed-loop control system

• The feedback loop only monitors the input and makes adjustments

• The feedback loop continuously monitors the output and makes adjustments to maintain the desired output.

What are the advantages of a closed-loop control system?

• No advantages, same as open-loop control system

• Higher cost, lower accuracy, and instability

• Better accuracy, stability, and disturbance rejection

• Less disturbance rejection, lower stability, and worse accuracy

Discuss the limitations of a closed-loop control system.

• Low cost, simplicity in design, and easy implementation

• High stability, low complexity, and no parameter sensitivity

• Unlimited control range, minimal energy consumption, and no need for sensors

• Stability issues, complexity in design and implementation, and potential instability with changing parameters

Provide an example of a closed-loop control system in real life.

• Traffic light system

• Car engine

• Thermostat in a heating system

• Refrigerator
