Electrical Engineering XYZ MCQs
Adding a pole to a system transfer function in terms of compensator represents which type of compensator:
- Lead-lag
- Lag-lead
- Lead
- Lag
Correct answer: 3. Lag
Explanation:
Adding a pole to a system transfer function in terms of a compensator represents a lag compensator.
Here’s an explanation to above Electrical Engineering XYZ MCQs
- Lead compensator adds a zero to the system transfer function, increasing the phase margin and improving the transient response.
- Lag compensator adds a pole to the system transfer function, decreasing the bandwidth and improving steady-state accuracy.
- Lag-lead compensator is a combination of lead and lag compensators, designed to achieve both transient response improvement and steady-state accuracy.
- Lead-lag compensator is not a commonly used term in control theory. However, it could potentially refer to a compensator that combines aspects of both lead and lag compensation.
So, given the options, adding a pole (which represents lag) corresponds to a lag compensator.
