Q6) A proportional controller, $K_p = 3$, is in series with a first-order system $G(s)$ in a unity negative feedback loop where $G(s) = \frac{4}{s + 2}$ a) Calculate the closed-loop transfer function $G_{ry}(s)$. b) Calculate the closed loop time constant. c) Calculate the closed loop steady state gain. d) Will a steady state error be present? Justify your answer with an appropriate argument. [10 Marks] Q7) Apply a Proportional Derivative PD controller to give a closed-loop damping of 0.7 and a closed-loop natural frequency of 5 rads/s. Assume a unity negative feedback loop and the system transfer function $G(s)$ is in series with the PD controller and is given by $G(s) = \frac{25}{s^2 + 0.1s + 0.25}$ [9 Marks]
