For a gain constant K, the phase-lead compensator

Home » Control Systems » Control systems miscellaneous » Question

For a gain constant K, the phase-lead compensator—

1. reduces the slope of the magnitude curve in the entire range of frequency domain
2. decreases the gain cross-over frequency
3. reduce the phase margin
4. reduces the resonance peak, M_p

Correct Option: A

For a constant gain, the phase lead compensator reduces the slope of the magnitude curve in the entire range of frequency domain. For more detail refer synopsis.
