Note: Applying a frequency response design approach is relatively challenging in the case of this example because the open-loop system is unstable. The pendulum module challenges students to not only model and control a pendulum, but also to learn about hybrid control systems by tuning a swing-up control system. Here is the Matlab code for this: To help determin the feedback gains, we use a method call LQR--linear quadratic regulator. which relates time with the acceleration of the angle from the vertical position
