Consider a simplified model of a rocket’s pitch dynamics represented by an inverted pendulum. The pendulum has length 𝑙, mass 𝑚 and the pivot point is controlled by a torque u. The angle 𝜃 is measured from the vertical upward direction, with 𝜃 = 0 representing the upright position (rocket pointing straight up). The equation of motion for the pendulum can be written as: 𝑚𝑙2 𝜃(𝑡) = 𝑢(𝑡) − 𝑚𝑔𝑙 sin𝜃(𝑡)
