The correct answer is: D. none of the above
A well-designed first-order control system has a large negative transfer function pole. This means that the system will respond quickly to changes in the input signal and will have a small steady-state error.
A small bandwidth means that the system will not be able to respond to high-frequency signals. A negative time constant means that the system will be unstable.
Here is a more detailed explanation of each option:
- A. small bandwidth
A small bandwidth means that the system will not be able to respond to high-frequency signals. This is because the system will have a high time constant, which means that it will take a long time for the system to reach its steady-state value.
- B. negative time constant
A negative time constant means that the system will be unstable. This is because the system will have a pole in the right-half plane, which means that the system will grow exponentially over time.
- C. large negative transfer function pole
A large negative transfer function pole means that the system will respond quickly to changes in the input signal. This is because the system will have a small time constant, which means that it will take a short time for the system to reach its steady-state value.
- D. none of the above
The correct answer is D. none of the above. A well-designed first-order control system has a large negative transfer function pole. This means that the system will respond quickly to changes in the input signal and will have a small steady-state error.
