Control Systems IB Computer Science Quiz

What is a feedback control system?

• A feedback control system is a system that amplifies the output of a process to achieve a desired state

• A feedback control system is a system that uses the output of a process to make adjustments to the input in order to maintain or achieve a desired state or performance.

• A feedback control system is a system that ignores the output of a process and maintains the input as is

• A feedback control system is a system that only makes adjustments to the input without considering the output

What are the components of a feedback control system?

• The components of a feedback control system are: input, process, output, feedback, and control

• Input, process, output, control, analysis

• Feedback, input, output, process, management

• Control, analysis, input, output, process

Explain the concept of error in a feedback control system.

• Error is not relevant in a feedback control system

• Error is the difference between the actual output and the input of the system

• Error is the result of a malfunction in the feedback control system

• In a feedback control system, error is the difference between the desired setpoint and the actual output of the system. It is used to adjust the control input in order to minimize the error and bring the system closer to the desired setpoint.

What is the difference between open-loop and closed-loop control systems?

• In open-loop control, the output is dependent on the control action. In closed-loop control, the output is independent of the control action.

• Closed-loop control systems are only used in industrial settings, while open-loop control systems are used in everyday appliances.

• In an open-loop control system, the control action is independent of the output. In a closed-loop control system, the control action is dependent on the output.

• Open-loop control systems are more accurate than closed-loop control systems.

What is the purpose of a controller in a feedback control system?

• The purpose of a controller is to increase the error signal and destabilize the system

• The purpose of a controller in a feedback control system is to compare the actual output with the desired reference input and generate an error signal to adjust the control input in order to minimize the error and maintain stability and performance of the system.

• The purpose of a controller is to have no effect on the control input

• The purpose of a controller is to ignore the actual output and reference input

Describe the role of sensors in a feedback control system.

• Sensors in a feedback control system are used to generate the output or process variable

• Sensors in a feedback control system have no role in detecting or measuring the output

• Sensors in a feedback control system only provide input to the controller for making unnecessary adjustments

• Sensors in a feedback control system detect and measure the output or process variable, providing input to the controller for making necessary adjustments to maintain the desired output.

What are the advantages of using feedback control systems?

• Some advantages of using feedback control systems include improved stability, accuracy, and the ability to adapt to changes in the system.

• Increased complexity and cost

• Inability to adapt to changes in the system

• Decreased stability and accuracy

Explain the concept of stability in feedback control systems.

• Stability in feedback control systems refers to the ability of the system to return to a steady state after being disturbed. A stable system will not exhibit excessive oscillations or diverge over time.

• Stability refers to the ability of the system to constantly oscillate without returning to a steady state.

• Stability in feedback control systems has no impact on the system's ability to return to a steady state.

• Stability means the system will always diverge over time and never return to a steady state.

What are the different types of feedback control systems?

• On/Off control, Off/On control, and Up/Down control

• Direct control, Indirect control, and Reverse control

• Static control, Dynamic control, and Kinetic control

• The different types of feedback control systems are proportional control, integral control, and derivative control.

Discuss the importance of feedback control systems in real-world applications.

• Feedback control systems are important in real-world applications because they help maintain stability, improve performance, and adapt to changes in the environment or system conditions.

• Real-world applications do not require feedback control systems

• Feedback control systems only cause instability and reduce performance in real-world applications

• Feedback control systems are not important in real-world applications
