Step 1

The open-loop transfer function \( G(s) \) is given by the product of the transfer functions in the forward path and the feedback path. The forward path transfer function is: \[ G(s) = \frac{K}{(s+1)(s+2)} \] The feedback path transfer function is: \[ H(s) = 0.2 Show more…

For the closed-loop control system below, calculate the value of the gain K, which will make the damping ratio of the closed-loop dominant poles ζ = 0.5. Show the operations you will perform on the complex plane and explain each step of your design in writing. Using the calculated value of the K gain, obtain the system's responses to unit pulse, unit step, and unit ramp inputs with Matlab or similar software.
