A control system exhibits slow transient response and high steadystate error. You are considering implementing controllers or compensators to improve both transient and steady$-$state performance.

Which of the following options are the most appropriate solutions for this scenario?

Multiple answers are allowed. The wrong answer will be penalized.

A$.$ Use a PI controller to reduce steady$-$state error and improve steady$-$state performance.

B$.$ Use a PD controller to enhance the transient response by reducing rise and settling time.

C$.$ Use a Lag compensator to reduce steady$-$state error and improve performance at low frequencies.

D$.$ Use a Lead compensator to improve steady$-$state error significantly.

E$.$ Use a Lead compensator to improve transient response by increasing system stability.

F$.$ Combine both Lag and Lead compensators for simultaneous transient and steady$-$state improvements.

G$.$ Use a PD controller to reduce steady$-$state error.
