Answer to Question #263303 in Electrical Engineering for sandhya

Question

The open loop transfer function {Please note: open loop TF is the forward TF times the feedback TF i.e., 𝐺(𝑠)𝐻(𝑠)} of a unity feedback control system is given by 𝐺(𝑠) = 25 𝑠(𝑠+5) . a. Calculate the natural frequency of oscillation, the damped frequency of oscillations, damping ratio, the exponential frequency, percentage overshoot for a unit step input. b. The non-zero and finite steady state error for the appropriate input depending on the system type. c. If the damping ratio is to be made to 0.75 from the original value obtained in 2 (a) using a tachometer feedback, calculate the tachometer constant 𝐾𝑡 and determine the percentage overshoot then
