what is the expression of the system's unit step response? Use Partial Fraction expansion to find the inverse Laplace transform of your expression. :) When K=29, calculate the damping ratio 3, natural frequency, and the location of the closed-loop poles, what type of time response is this (underdamped, overdamped,undamped)? ) What is the general expression of the system's unit step response when K=3, and K=4?You do not need to perform partial faction expansion here, just need to provide the general form of the expression based on the pole values.
