1 . Sketch a diagram of the closed-loop system for the speed control in order to maintain height at a set point, and write down the closed-loop transfer function.

2. Plot the system response.

3. Find the feedback gain that results in a step response that is less than 3% overshoot, and note down the rise time. Provide a plot and state the gain.

4. Design a simple controller such that the step response of 3% overshoot is obtained. Note down the rise time, pole positions, and the feedback gain.

5. Plot the final step response.
