What is a control system?
A type of feedback mechanism
An arrangement of subsystems and processes
A single entity that operates independently
A method of data collection
Which type of control system uses feedback?
Hybrid Control
Closed-Loop Control
Open-Loop Control
Feedforward Control
What does positive feedback do?
Reduces error
Amplifies error
Prevents error
Maintains stability
Which of the following is an example of negative feedback?
A microwave oven running for a set time
An air conditioner adjusting based on room temperature
A traffic light adjusting based on expected flow
A microphone causing screeching noise
What is dead time in a process?
The time taken to reach steady-state
The time taken for input to change
The delay before the system starts responding
The time taken for feedback to be processed
What does the time constant indicate?
The speed of the system's response
The overall gain of the system
The amount of energy stored in the system
The delay before the system starts responding
Which type of control is proactive?
Closed-Loop Control
Feedforward Control
Positive Feedback
Negative Feedback
What is the effect of a higher resistance in a system?
Decreased dead time
Increased stability
Slower response time
Faster response time
What characterizes an underdamped system?
Slow response with overshoot
Oscillates before settling
Fastest response without overshoot
No overshoot
What does process gain determine?
The stability of the system
The type of feedback used
The delay before response
The change in output due to input change
Which of the following describes a stable system?
Has no feedback mechanism
Returns to equilibrium after disturbance
Oscillates continuously
Deviates further from the setpoint
What is the primary function of feedback control?
To predict disturbances
To operate without adjustments
To maintain system stability
To amplify errors
What is an example of feedforward control?
Steam boiler control
Microwave heating
Thermostat operation
Air conditioner adjustment
What does a higher capacitance indicate?
Faster response to changes
More energy storage before change
Less stability in the system
Increased dead time
What is the main characteristic of a critically damped system?
Slow response with no overshoot
Oscillates before settling
Fastest response without overshoot
Returns to equilibrium slowly
