Addition of zeros in transfer function causes which of the following?

Solution (By Examveda Team)

Addition of zeros in transfer function causes lead-compensation.

Lead-compensation is achieved by adding zeros to the transfer function, which advances the phase of the system and improves the transient response.

In a lead-compensated system, the zero increases the system's responsiveness by increasing the phase margin, leading to a faster response.

Lag-compensation and lead-lag compensation involve different configurations of poles and zeros to achieve specific performance characteristics.
