Understanding Phase-Lead Compensation
Phase-lead compensation is a technique used in control systems to improve stability and performance. Let's analyze why option 'D' is incorrect.
Key Characteristics of Phase-Lead Compensation:
- Increases System Bandwidth:
- Phase-lead compensation increases the bandwidth of the system. This allows the system to respond more quickly to changes in input.
- Increases Gain at Higher Frequencies:
- It provides an increase in gain at higher frequencies, which enhances the system's ability to track fast changes in input signals.
- Fast Transient Response:
- This compensation technique is particularly beneficial when fast transient responses are desired. It reduces the settling time and improves the overall responsiveness of the system.
Why Option 'D' is Incorrect:
- Decrease Rapidly Near Crossover Frequency:
- This statement is misleading. In a phase-lead compensation network, the phase margin is increased, and the gain does not decrease rapidly near the crossover frequency. Instead, the network is designed to maintain or even enhance the gain within the crossover region, leading to a more stable and responsive system.
Conclusion:
In summary, phase-lead compensation is characterized by its ability to enhance system performance. It does not lead to a rapid decrease in gain near the crossover frequency, making option 'D' the incorrect statement.

Lead compensator:
Transfer function:
Transfer function:
If it is in the form of 
then a < 1
then a < 1If it is in the form of 
then a > b
Maximum phase lag frequency:
ωm = 1√Ta
Maximum phase lag::
then a > bMaximum phase lag frequency:
ωm = 1√Ta
Maximum phase lag::
ϕm is positive
Pole zero plot:
The zero is nearer to the origin.
Filter: It is a high pass filter (HPF)
Effect on the system:
Filter: It is a high pass filter (HPF)
Effect on the system:
- Rise time and settling time decreases and Bandwidth increases
- The transient response becomes faster
- The steady-state response is not affected
- Improves the stability
- The velocity constant is usually increased
- Helps to increase the system error constant though to a limited extent
- The slope of the magnitude curve is reduced at the gain crossover frequency, as a result, relative stability improves
- The margin of stability of a system (phase margin) increased
