step by step please . i need the code for the lab

Objectives To verify the effect of pole location upon stability. To verify the effect upon stability of loop gain in a negative feedback system. Minimum Required Software Packages MATLAB, Simulink, and the Control System Toolbox Prelab 1. Find the equivalent transfer function of the negative feedback system of Figure P6.22 if G(G)z and H) +1 s(s + 2) 2. For the system of Prelab 1, find two values of gain that will yield closed-loop, overdamped, second- order poles. Repeat for underdamped poles. 3. For the system of Prelab 1, find the value of gain, K, that will make the system critically damped. 4. For the system of Prelab 1, find the value of gain, K, that will make the system marginally stable. Also, find the frequency of oscillation at that value of K that makes the system marginally stable. 5. For each of Prelab 2 through 4, plot on one graph the pole locations for each case and write the corresponding value of gain, K, at each pole Lab 1. Using Simulink, set up the negative feedback system of Prelab 1. Plot the step response of the system at each value of gain calculated to yield overdamped, underdamped, critically damped, and t stable responses. marginally 2. Plot the step responses for two values of gain, K, above that calculated to yield marginal stability 3. At the output of the negative feedback system, cascade the transfer function
